Pardon us if we don’t swipe right, but we’re just selling digital thermometers here. This one, from HomeMedics®, is 8” long but the 3-1/2” probe folds away and tucks into the 4-1/2” long handle. Readout is 1” x 1/2” LED display, shows -40 to 450F, -40 to 232C, and has a hold button to freeze display. Made for cooks, but because of its wide temperature range it doesn’t really care what or whom it’s measuring, heat-wise. Powered by a pair of common CR2032 batteries (included). 

This clear plastic curvy bottle holds 10 oz, and has rounded shoulders and a flared bottom, not unlike a popular chocolate milkish drink container. Stands just a tad over 7" x 2-1/4" dia, and comes with a non-gasketed screw cap with seal. Mouth is 1-1/4” ID. Great for holding tiny parts, sand art and DIY soaps.

You need this keychain with a handy 3” long x 1-1/8” wide white plastic compass/thermometer combo on a 7/8” slip-ring. From the “Keychains With Purpose” line of products (our new favorite name), it’s made for folks devoted to being prepared. You know who you are, and so do we.

From Brinks®, this personal security alarm has an IR sensor that will trip a 120dB siren or door chime when anyone enters the sensor’s 100-degree x 12-foot range. Measures 4-5/8" x 2-3/8" x 1-3/4" in a white plastic housing with a 1-3/4" x 1-3/8" lens. Mounts via a 5/32” keyed slot or an included 1” ball-and-socket bracket. Could also be set on a dresser or desk in a hotel room. You add (4) “AAA” batteries.

In Surplus World, it often does. That teensy error on the cardboard tag brings you this snazzy blue-speckled enameled steel coffee mug, the sort that legions of prisoners have dragged along the bars of their cells in legions of movies, at a price that is freeing. Maybe has a cowboy look to it, too. Holds, yes 10 ounces, and measures 3-1/8" x 3-3/16" dia.

Might be a slight exaggeration, but Pierre Vernier was born in 1580 and people were really short then. In any case, our aluminum Vernier caliper is 29” long and will measure up to 24” (61cm) in 1/16” (1mm) increments. Has 2-3/4” long jaws and a lock screw. The resolution on the Vernier scale is 1/128” - 0.05mm. Please Note: Your entire order will ship standard ground when purchasing this item. Contact us for expedited shipping information. Thanks!

That flat-screen TV you paid a fortune for has been sitting on a coffee table long enough. Time to wall-mount it like all the television sets on television shows. Our full-motion mount fits standard LED wall mounts, holds sets from 23” to 50” and up to 44 lbs, can pull away from the wall up to 13-1/2”, tilts 5-15 degrees, and swivels 90 degrees right or left.

You do have tubes, don’t you? This 10-piece set of wire brushes includes (5) each in brass and stainless steel, all 12” long, with 4” long bristle sections with 1/4”, 5/16”, 3/8”, 1/2” and 3/4” dia bristles. Loops on the end are for hanging above the bench where you do your tube cleaning.

The world does not live by screw caps alone. These thick amber glass vials are 3-5/8" tall x 1-7/16" dia with a lip and 1-1/8" ID mouths. They’ll take a #16 cork, which we’ve included to save you time because we’re thoughtful that way. Made in the USA. Holds about 1.35 oz. with the cork, and about 2 oz. without. (That's about 40ml and 60ml, respectively, if you're into the metric system.) 

These translucent plastic three-ring binders have 1” rings and measure 10-1/4” x 11-5/8”. You pick the aqua color; the frosted white with a transparent sleeve on the outside front for a title/contents sheet; or the textured translucent white with clear sleeves on the inside of both front and back covers.

Most likely. Luckily we have just the Brain Teaser to take care of that for you. This 2-1/2" green (or black) and natural wooden puzzle looks like a Rubikish cube but is actually more like a snake made from 3/4” wooden cubes and held together by a pretty elastic elastic cord. Unfolds to a zig-zag snake approx 14’ long and ready for you to reconfigure back into a cube. We’d show you how, but our brain has to remain unteased for copywriting purposes.

What we have here are 96-sheet, white genuine Post-It  note pads, 4” wide x just shy of 3” tall with adhesive strips on the top edge. Plus, for mysterious reasons, the samples we received have (5) pink capital letter Fs strung across the top margin. Just ignore them, unless your name is Frances, Fiona, Frank, Felicity or Fanny--or Fogarty, Fletcher, Fox or Fernandez, but don’t ask for a discount because they’re already cheap. You will probably get some letters other than F, too. That’s why they call it surplus.

Light up your feet for safety’s sake with this pair of bike pedals with (8) red LEDs in each. Measure 4" x 2-3/4" x 1-1/4" with the standard threaded axles, and powered by internal dynamos (we really like saying “internal dynamos,” and now you can too) that will make the LEDs glow in either direction of rotation.Includes a free wrench for installation, and in case you weren’t paying attention in physics class, the left pedal is necessarily reverse-threaded.

How big are your locking pliers? This giant pair, in hardened steel, will grip the largest vices in captivity at 14” long with serrated 1-7/8” jaws that adjust from 11/16” to a gaping 2-1/4” ID. Tighten via an 11/16” bolt. Easy to locate, too, in a popsicle-ish lime green.

It’s faux hurricane season here in Chicago, and time to break out our faux hurricane lantern. Regardless of the season, though, it’s great as an accent light in any room, back yard or camper. Stands approx 10” tall x 5” wide, in steel with an antiquey copper finish. Has a carrying/hanging handle, and a push-button turns on both a 25-lumen flickering LED flame and an 80-lumen bright-white LED. Comes with (4) “AAA” batteries.

Really. Our each is a 10-foot roll of 1/2” wide, self-adhesive magnetic strip. Flexible, too, so the craft, kitchen, classroom and cubicle uses are limited only by your imagination! (We heard that on an infomercial once--we really don’t know much about your imagination, but we always assume that is it vast and nimble.)

This tall, straight, clear plastic bottle is a flaskish shape, measuring 8” tall x 4-3/8” wide x 2-3/8” at its thickest, in an elliptical profile. Holds 32 oz and it’s clear, so you can fill it with colored sand or make your own “find it” game. Comes with a gasketed screw cap on a 13/16” ID mouth.

From Scientific Explorer®, the people who start kids off right, come these self-contained kits for kids 6+.

Environmental Science teachers, how about showing your students how to test water’s visibility and hence turbidity--or its opposite, clarity--with our freshwater Secchi disk? (We thought you’d like the idea.) The disk is just under 8” dia with an integral weight and alternating black and white quadrants, attached to a 72-foot nylon cord marked every foot with a hash mark. Just lower it into water and you’ll have your results, and teaching points.

We’re out of red; you’ll have to make do. These fluorescent yellow paint markers from Krylon® have a 3/16” wide wedge tip. Paint dries within 15 minutes, the same time it took the Music Man to meet Marian the Librarian at the footbridge, so be patient. Can be used on fabric.

This small stainless steel fine-mesh filter is 2" dia x 1-1/2" tall. It has fine mesh sides, a solid plastic bottom and slight lip around the top. Nice for small filtering jobs, but would also make a passable basket for a gerbil hoops game.

You’ll need a little trouble light, and this is the littlest one we’ve ever offered. From iZoom®, it’s a compact 8-1/4” long with a 15-element, intense COB LED in a 3-3/4” x 2” reflector with cage, and a 4” long folding hanger. Has a disc magnet with a 5-lb pull on the bottom. Comes with a trio of “AA” batteries and is available in red, black, yellow and orange to complement its classic design. We’ll pick the color because you have enough to worry about.

A smaller version of the monster flood lights most of us can’t afford, this one’s rechargeable from iZoom with a 600-lumen 10W COB white LED with a 2-3/4" x 1-3/4" reflector in a water- and dust-resistant 4-3/8" x 3-1/4" x 4-1/4" with a padded 3-5/8" handle and adjustable 6-1/2" x 5-1/4" H-shaped base plus an adjustable mounting bracket. Includes a cigarette-plug charger and wall plug. Runs a little under 2 hours on a full charge.

Voted most likely to attract by the judges, this magnet has the relative strength of 10 men. A shiny silver 1/2" cube of neodymium magnetism, it packs approx a 15-lb pull. If our boss Pat were that strong he could lift 2,160 lbs! Besides its superpower strength, this beautiful cube also would improve the looks of your fridge or bulletin board to no end.

We feel sorry for those flesh-colored bandages that are just trying to hide. Stand up and be healed with bandages that make a statement! Say Oink with this box of (15) sterile photo reproductions of a raw bacon slice, plus a bonus plastic pig in every box.

This 2-5/8" assorted colors aluminum carabiner has a canvas strap with a rubber gasket on it to grab onto the top of your standard water bottle with a 7/8" cap. This makes it great for biking and hiking, too. Also has a slip ring for sundry other stuff.

Not fishnet stockings, but netting for actual fish, direct from the U.S. Army (you'd think Navy, wouldn't you?) in olive drab. It's a survival thing. You get a 10-foot x 5-foot net made of 3/4" squares individually knotted from twisted cotton/nylon, so the net won't unravel if torn. Might have a slightly musty aroma (but definitely not fishy) that a little sunshine time will fix. Great for maritime-theme decoration, bible-camp plays (filled until breaking, walking-on-water background prop…) or, we suppose, fishing. And perfect if you want to go to a costume party as Poseidon.
