And more. This accessory kit for smart phones (works with iPhone, Samsung, HTC, iPad, tablets and many others) has a 2” long clip-on bracket with screw-in macro, wide-angle and fish-eye lenses. Paul loves his kit and he’s our optics expert. Use the macro for insects, coins and diamonds. Fish-eye and wide-angle for great visual effects. Includes a little pouch to carry it all in, and tiny lens caps.

Note: Two lenses come threaded together to conserve space. 

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.

We don't like to brag, but it's tough not to in a case like this. This is a wonderful pen-shaped laser pointer, 5-1/4" long, flat black or silver with gold pocket clip and head. It throws a red point a loong way (we've thrown it two city blocks at night, and it would've gone farther, but buildings got in the way). And what are we so proud of? We've seen a very similar item-not identical, mind you, but essentially the same-in one of those glossy, toys-for-grown-men catalogs. Their price? $20! We're proud not to be profit-mongers, buy it here and you can take pride in your smart shopping habits. Batteries included.

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.)

The manufacturer calls it the Quik Fix Zipper but they obviously don't pay a copywriter to create dumb puns. So...it's the Zip-a-dee-doo-dad, a set of (3) replacement zipper tabs/sliders in graduated sizes (#3, #5, and #7) that come apart so you can slip then onto a zipper and tighten them with a little thumbscrew. Handy for busted jackets and sleeping bags. Even handier for pants. Removeable and re-usable.

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.

Or garage, or hallway--anywhere that’s wireless in the bad sense. CJ calls this “another retina scorcher” from iZoom® because of the brightness of the COB lights. Fixture measures 3" x 4" x 13/16" in white plastic with a big rocker switch that activates the 1” white COB LED in its center. Powered by (4) “AAA”s, included. Mounts via self-adhesive hook-and-loop pads or the pair of little disc magnets on the back.

We know you need accent lights, and we know you hate paying electricians. So…grab this 7-3/8” long x 1-1/8” x 1/2” silver iZoom® light bar, peel the back off the magnetic strip it comes with and stick it up anywhere. Has (10) LEDs and is rated for 200 lumens behind a frosted white lens. Has a motion and light sensor, so it only accents stuff in low light when it senses movement, which saves on the (4) “AAA” batteries it comes with. Lights for a 3-minute duty cycle.

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.

Works on all of them except the ones stuck to your eyeballs. Corrosion-Be-Gone is a gel made to remove the schmutz from all types of battery terminals, circuit boards and contacts, on everything from cars to computer boards. Our each is a 0.3 oz jar.

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.

Spin this spindle and watch it turn in perpetuity!!  Well, for a long time anyway.  Inside the 5-1/2" long colored plastic spindle are magnets which are repelled by magnets in the 5" x 3" black plastic base.  The variously colored spindle floats in the air above the base thus virtually free of normal friction. Nifty desk toy named "Revolution".

Please note #91664 with flashing red lights was incorrectly advertised, that item is not available.

Freeze-dried Neapolitan ice cream, 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. 

Who doesn’t? Try this set of (5) low-profile white, red, green and blue LED accent light pucks. Measure approx 2-3/4” dia x 1” deep, they’re powered by (3) “AAA” batteries each, included and you’re welcome. Turn them on manually to switch between colors, or use the wireless remote. Also has bright or dim white settings, 4- and 8-hour cycles, and (12) color permutations for your color morphing pleasure. Remote includes a replaceable coin-cell battery and has a 15-foot range. Lights come with foam tape for mounting.

Our common red or green pointer too blasé for you? Make your point violetly with one of these rare violet laser pointers. Its non-slip black rubberized case with silver accents is 6-1/8” long x 7/16”dia, with a momentary switch and a pocket clip. Includes the (2) “AAA” batteries you’ll need. You’re welcome.

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.

Georges Braque would have loved the tiny ice cubes that come out of the lid of this plastic box, but then he was a cubist. You'll like them just because they're cute. Pop (20) 15/16" cubes out of the tray, then store them underneath in the 7" x 6-1/4" x 4-1/8" plastic box.
