Little Glass Ampules
Terrific little glass bottles with looooong necks, in the shape called "Ampules". About half the total height is a standard cylindrical shape, at the top of this there is shoulder and above that, is an elongated tulip shaped neck. All are clear. They may have either a blue, gold or ground band on or below the "bulb" of the tulip. Bud vases for a single forgetmenot, decorative holders for colored sand or water, delicate vials for perfumes and essences, whatever the use, you just won't find them in stores. The 2 ml is 75mm tall with a 4mm neck and is 11.5mm at the bottom while the 5 ml is 88mm tall with a 6mm neck and is 16mm in diameter at the bottom. Looking for bulk savings?

Needle File Set
Miniature 5–1/2" steel needle files. They come in the usual assortment of flat, wedge, triangular, and round shapes, (10) in all. They seem to be pretty uniformly fine with none that we would call coarse. Made in China, they come in a vinyl carrying case that snaps shut. Not as classy as some of the sets we have seen in the $18.00 range, but perfectly serviceable for most applications. And at a third the price.

Mashers and Smashers
Porcelain mortars and pestles. Great heavy duty mortars, with sides that are easily 5/16" thick on the smaller ones, and up to 1/2" on the larger. The mortars are glazed outside, but rough inside, the better to grind, and have a pouring lip. The business ends of the pestles are unglazed, while the shafts are glazed. Very functional, very good looking!! So grind your own spices or lab concoctions as you prefer. You get a mortar and pestle as a single order.

Heat Filter
A little pricey for a 2" x 2" x 1/8" thick piece of clear glass, until you figure that this is pretty darned talented glass, and that it filters heat and reflects infrared and ultraviolet rays. Then it's a bargain!

LCDs
These liquid crystal displays are raring to go. As soon as we can get Mary Ann to stop playing with them we'll pick out (5) assorted displays for you. (She keeps zapping them with static electricity to see what pops up. Mary Ann is easily amused.) Sizes range from 1-3/16" x 2" to a few as large as 5" x 10". They're unused. Some have pin leads, some have traces right on the wafer. Either way, they're a terrific bargain.

Circuitry diagrams are available online at several sites.

Comes in a very nice black, soft carrying case with a shoulder strap, a hook-and-loop closure, and a handy chamois tucked inside.
