The kids need presents for all the grandmas and great-aunts? You volunteer at the nursing home and need token gifts for your L-O-Ls? And your eyes aren't so good, either? Our each is really half a dozen pretty little magnifiers with round lenses and fancy handles. The handles are silver-bright (hard to believe they're aluminum) and all different. Each has a discreet hole in the tip for a jump ring so it could be worn on a necklace -- but it would look just as pretty on a desk. The overall length of the (6) magnifiers varies from about 3-3/4" to 5", the lenses from 1-1/4" to 1-3/4" dia. All are approx 2X magnification. Mary Ann's pick of the month.

A really cool mini drill set for your mini projects! The 7-1/4" long aluminum push drill for delicate work comes with (1) 1/16" and (1) 1/32" collet, and (20) bits that fit them. The bits are #61 through #80, some so needle-thin they could add tear ducts to a fashion doll. They come in a mini case marked with the number and size of each bit in mils.

Getting tired of buying them and trimming them and losing them? Get rid of wicks altogether with this nifty little alcohol burner with a copper capillary tube in place of a cotton wick. Burns 90ml of denatured alcohol and comes with a heat shield (packed inside the reservoir) and a burner cap. Don't forget to remove the little rubber plug - it's there to cover the holes in the copper tube when not in use. And this is lab equipment, so resist the temptation to use it under a chafing dish; initially, it flares up a tad more than is good for Swedish meatballs.

Inside the lab, it's a standard translucent-white, LDPE-plastic wash bottle, 500ml/16oz, measuring 2-3/4" dia x 6-3/4 tall with a screwcap and a right-angle, 5/16" dia nozzle. Outside the lab, it's so pleasing to squeeze and squirt with that some of us keep them in the kitchen.

Display a pair, in fact. Our each is (2) clear flexible-vinyl doll display cases with creamy-white plastic bases. The bases are 6" square with 15" tall x 5-7/8" square vinyl cases with clear vinyl tops. The lightweight cases fold for storage. Each case comes with (2) stands: (1) waist grip that adjusts from 6-3/4" tall to approx 10" tall; and (1) 6-3/4" tall saddle style. Includes (2) self-adhesive 1/2" x 3-1/8" brass plates for names. Not into dolls? That waist clamp thing would also be just right for showcasing a prize carrot.

We've never seen anything quite like these little clear glass vials, which means they must have myriad uses, particularly at this price. The large one is 1-3/4" tall x 15/16" dia with a shoulder and a 1/2" ID lipped mouth on the top, leading into a 1" deep conical cavity. The bottom has a 5/8" mouth, with an internal lip, and opens into a cavity around the little conical reservoir. So you can fill either end. Which would hold maybe a couple of ccs one way, or 1/4 oz the other way. The little one is the same, but is 1-9/16" tall x 5/8" dia and a 1/4" ID mouth on top, 7/16" on the bottom. We're thinking obscure lab experiments, or chimneys for streetlamps in model railroads. Or something.

So we're pricing these borosilicate boiling flasks to move quickly. We've got (3) sizes, all with slightly flattened bottoms, each with a single, discreet, capacity mark in white. While the actual physical size can vary slightly, the volume remains the same. The 1000ml flask is 9-5/8" tall OA x 5-5/8" dia with a 1-5/16" ID mouth, and a lip. Takes a #7 rubber stopper. The 500ml flask is 6-7/8" tall OA x 4-1/8" dia with a 1-3/16" ID mouth, and a lip. Takes a #6-1/2 rubber stopper, but a #7 will work. The 250ml flask is 6-1/8" tall OA x 3-3/8" dia with a 1-1/32" ID mouth, and a lip. Takes a #5-1/2 rubber stopper, but a #6 will do the job.
