First, get rid of that carpeting. Then get this set of multiple standard 1.5mm spring bars. You’ll get between 7 and 10 of each in a dozen sizes (100 pieces altogether) from 8mm to 19mm, plus a double-ended tool to help you swap them out in the first place.

Diamond files never wear out, hardly, unless you file diamonds with them. This 10-piece set of diamond files has an assortment of wedges, flats, points and triangle files, all 6” long overall and up 5/16” wide.

From 3M comes this extra-festive packing tape because we heard you’re bored stupid with that brown stuff. You’ll get a (6)-pack of tape, 1-7/8" wide x 40 feet, in pink, aqua, red, lime-green and other colors, in stripes, zig-zags, polka dots and other festive patterns.

The package calls these “Prospector’s Choice” and suggests using them to “collect fine gold particles with ease.” Feel free, but we like them for labs and crafts--anywhere that dropper dispensing occurs. Our each is a package of (50). Great for labs, crafts and hobbies.

We love NASA and so do you, or someone you love does. And with the 50th anniversary of the moon landing this year (July 20), why not show your support by sticking a bunch of classic NASA “meatball” logos on your stuff? You know the one--the blue sphere and white stars with the NASA name in white, a red chevron slashing through it and a white orbiting swirl wrapping it all together. You’ll get (15) logo stickers in 1” dia ; a 3-1/2” logo sticker; a 3-1/2” window cling logo; and a good, old-fashioned 10" x 2-3/4" white bumper sticker with the logo and the following phrase: “IT’S NOT ROCKET SCIENCE! (OH, WAIT, YES IT IS!)”. Hard not to love that aerospace-engineer humor.

Just the one, actually, but it’s been sliced in half so the pair is perfectly symmetrical and mighty pretty. Although ammonites have been extinct for 65,000,000 years, we’ve got their approx 1” dia fossils for you. Our each is a book-matched pair of polished ammonites fossils of a single critter halved and polished to a bright symmetrical shininess. The colors vary from light tan to dark brown and we’ll pick because we have impeccable ammonitical color-shade taste. And yes, they’re just screaming to become cuff-links or earrings.

Whatever you call them they are super handy. Used for suturing, these are carbon-steel straight-locking needle holders, 5” long with narrow serrated 7/16” tips. And yes, you’re permitted to use them for other stuff if you’re not a surgeon. (Or even if you are a surgeon, actually.)

Take these (250) little translucent beads into the sunlight and they burst into assorted colors faster than you can say "assorted colors." How do they do it? Well, they're UV-reactive, that's how. Mostly pink, purple, rose, yellow and cream and they fade to a nice pearly color inside. Amaze your friends at picnics. Beads measure 5/16" dia x 1/4" with a 5/32" bore.

Our best and prettiest-ever slices of polished agate, showing concentric rings of natural and dyed colors. The slices range from 3" to 4-1/2" across and from 1/8" to 3/16" thick. We've seen samples from milky white to blue, purple, red, yellow and brown. No two alike, by definition. We'll choose. Think scientific specimens, framed art, coasters, trivets, paperweights, or skipping stones for rich kids who don't want to search the beach for flat stones.

And then give us a little tweeze, and a couple more for luck. Our 4-piece stainless steel tweezer set includes: 4-5/8" long bent tweezers; 4-1/2” fine point; 4-5/8” cross-locks; and 4-1/4” blunt-tip stamp tweezers with 1/4” wide tips for you philatelists.

These're pleasing tweezers, these are. They're clever cross-lock tweezers, 6" long with wood-grain grips and 1/2" long, serrated 90° jaws that grip tightly. The handy cross-locks will lay flat on their backs to hold stuff, like wires, while you solder.

You've come to the right place. Here's a humongous version of the always popular pink eraser. Ours is 3/4 of a pound and 6" long x 2" wide x 1" thick. The top says "For Really Big Mistakes" but that, not surprisingly, rubs right off if you don't like it there.

The Clay People were all gray in Flash Gordon’s world, but this 24-piece set of modeling clay comes in (24) colors, including the non-rainbowish black, white and gray because a lot of stuff is, after all, those colors.
