Measure temperatures without a touch with this digital infrared laser thermometer. Pistol style, 6" long with a 3" nose and 1.5" back-lit LCD readout. Point the guide laser where needed and measure from -58 to 716 F, and -50 to 380 C. Accurate to +/- 2 degrees C. Handy for science projects, HVAC work and making sure your glass of wine is the perfect temperature. You add a pair of "AAA" batteries.

Hang it all with this set of (10) magnetic hooks. The 1-3/16" long x 9/64" hooks screw into 1-3/8" dia magnetic bases with an approx 8-lb pull, which is lighter than most jackets and keys. Good for horizontal or vertical mounts, and dandy for adding hooks to gym or school lockers.

This pocket-sized mini-flashlight has (9) 405nm ultraviolet LEDs and myriad uses, from checking U.S. currency to working the door at your ultra-hip downtown clubs, spotting radiator and transmission fluid leaks, mineral identification, and (yes, it's true) locating lost scorpions in the dark. Measures approx 3-3/4" long x 1-1/8" dia with knurled sections so you won't lose your grip, and a wrist strap in case you do. You supply (3) "AAA" batteries and the scorpions.

These silicone hot pads double as trivets or oven mitts. Measure 7-1/8" dia x 3/16" thick with 1/4" honeycomb indentations to further dissipate heat, plus a 3/8” hole near the edge so you can hang them up. We’ll pick one in red, blue, green or orange, and you can redecorate your kitchen to match. They also double as the world’s safest frizbees.

But here’s a nightlight for your driveway or backyard anyway! By iZoom®, and direct from the late-night infomercials, this solar-powered light has (8) white COB LEDs across its face and a rechargeable lithium battery inside. It’s motion and light-sensitive, and shines brighter when it senses motion . Measures 4-1/2" x 3-3/8" x 1-3/4" and comes with a self-adhesive pad on the back, plus screws and mollies. You supply the darkness. Sells for $12.95 at a popular home retailer.

Freeze-dried Neapolitan ice cream sandwich, it says on the foil package, just like the astronauts got if they ate all of their freeze-dried peas. Not frozen, of course, or even chilled, but you get one yummy pack, ready to eat, just under half an ounce, which is more than you'd think. 

Direct from our faithful hospital supply suppliers--handy dandy (and brand new) tubs for storing, sorting, scrubbing, or schlepping toys, mittens, craft supplies, chicken feed, whatever. In yellow/gold pretty-much-indestructible #5 plastic, each is approx 13" x 10" x 5" deep. (Some might be a tad smaller). They have lips and rounded ends, nest when not in use, and are graduated inside from 2 to 6 quarts.

Steampunk alert! Also…model and jewelry maker alert! This pair of 10X acrylic doublet loupes is mounted on black eyeglass frames and flanked by LED lights powered by (2) included CR1620 button cell batteries. These are for close work only, from 1" to 1-1/2", and can focus only one lens at a time (not both on the same object) so if you’re a steampunker looking for a new accessory, plan on perching this rig on your pate or chapeau.

Call it a gonzo version of our best work-light, this 4-5/8" x 2-1/4" x 1" cigarette-pack-size light has (60) white LEDs in a 3" x 1-1/2" window with a bright mode and a way brighter mode that would blind a turkey vulture, plus (4) more for a standard flashlight mode. Includes a flip-out easel, hook and a disc magnet. Comes with (3) "AAA"s. Manufacturer rates this bad boy at 900 lumens. 

This isn't a book, but it's definitely book-ish. Looks like a leather-bound volume from the Bodleian but it's just a little wooden box, approx 8-1/2" x 5" x 2" (7" x 3-7/8" x 1-5/8" inside) that's perfect for stashing the jewels, cash, or whatever you need to stash in plain sight on the shelves.

BACK BY POPULAR DEMAND!!! Mystery boxes of stuff like what you see in the catalog. Maybe we had a little left but not enough to continue the listing. Maybe we only got a few as part of an odd lot. Maybe we lost some, and just found them in the warehouse. You will get items which originally listed for at least $25.00 total in our catalog (or would have, if we had enough). You pick. The “electro-mechanical” box has things like motors, switches, hardware and components that are useful parts but want to be worked into something bigger. The “consumer” box has more ready-to-go type items, and things that don’t have as technical a flavor, like bottles, toys, books, and giant rubber bands. The fun is in the mystery and surprise. Perfect if you don’t know what to give Aunt Maude and Uncle Ned, or if you can’t decide how to bring your order up to the minimum. Every couple of months the contents will keep changing, so even if you have gotten a box before, feel free to order again! (Please note: Ordering multiple boxes at the same time will result in duplicate items.)

This microfiber duster starts out 11” long and the telescoping 4-draw handle extends to over 2 feet, if you count the headful of 1” long wiggly dust-busting fingers on top. Can you say recessed lighting? Ceiling fan? We’ll select one for you in a flattering purple, lime green, pink or light blue. Would also make a can’t-miss baton for a high-school band director.

Looks like an antacid tablet, a white disc 13/16" dia x 3/8" thick, but drop it in water and the rayon instantly expands into a 9" x 13" reusable wipe. Can you say handy? No mother should ever leave the house without a few in her purse and no glove compartment is complete without a handful. Click here and watch the magic! 

These big, 4" long steel safety pins are practically jewelry in their own right. You get a 5-pack in assorted colors--gold, black, metallic pink, blue, green or others. Perfect for closing buttonless sweaters and tops or securing scarves in fascinating configurations.

Four fine funnels, a fantastic fare. Sturdy plastic, the biggest is 4-1/8" dia at the mouth, with a 1/2" dia spout, the smallest has a 1-7/8" dia mouth, 1/4" spout. The other (2) are in between. Frankly, it's freaky fun flowing fluids from four funnels!

Dogs just wanna have fun. You can help by getting yours this 3” dia thick flashing rubber ball toy. (It’s a great present for Rin Tin Tin’s birthday, September 10, which most dogs celebrate.) In black rubber with 1-3/4” dia insets of translucent red, yellow, green and blue rubber spikes (good for their teeth) with flashing LEDs behind them, activated by bouncing. Excellent for nighttime fetching.

Don't toss it and buy a universal remote. (How many things are really universal, after all?) Try this jar of Keypad Fix, designed to clean and restore conductivity to the carbon on the keys and the copper PC board pads that make up the rubber-coated switches on remotes, game controllers, and security keypads. Contains enough to coat over 200 button contacts.
