We have obtained a large number of real natural corks ranging across the popular sizes used in science labs to seal vessels (drill your own holes for glass tubing, etc), use as floats and as a great craft item. Or just use them to seal bottles that don't have closures or cry out for a decorative seal.

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.
