Pat's been hanging around the medical supply house again. We now have a boatload of rubber stoppers, the kind you see on bottles of liquid medicine, crimped down with an aluminum collar. (Pat didn’t buy the aluminum collars.) The medicine is removed via a hypodermic needle through the stopper. The rubber stoppers come in a friendly orange and fit (13 mm) dia openings. The orange are 9/16" across the top, which has a dimple in the center, and 9/16" top to bottom. Why would you want them? Because they'll fit many of the small wide-mouth and slope-shouldered bottles in our Bottlemania listing. Pat's really good!

They're gray rubber stoppers, 3/4" dia at the top, threaded at the bottom to fit 17mm ID bottles. They're 7/8" long OA, with a threaded portion 7/16" long. Which doesn't matter a whole lot if you're using them for their most obvious use, which is to glue them to your neck for the world's absolutely best Frankenstein costume!

Black rubber stoppers for all your unmet rubber-stopper-top needs. You pick the bored (for laboratory tubes or making shakers) or the unbored, if you need closure.

So Pat went a little crackers and bought approximately 897 gazillion #00 rubber stoppers, enough to stop up every small test tube in every high school science lab from here to Osaka. You'll get a bag o' (1,000) of them. We know you'll find a crafty use: tiny bowling games, non-conductive earrings and necklaces, little bumper car bumpers, traffic cones for cockroaches, stubby guitar picks.... In black rubber conic sections, 1" long x 10mm (0.39") at the bottom x 14mm (0.55") at the top, or vice versa.
