Our smallest rubber stopper, size #00, only $0.20 for one with discounts for quantity, is our smallest. It measures 26x15x10mm (~1x11/16x7/16", height at top, bottom) and fits our 13x100mm test tubes.
In addition to being used as a rubber stopper for vials, these small rubber plug stoppers can plug 15/32-1/2" holes in pipes or hummingbird feeders.

I'm using a couple of these as stoppers (and they work great), but the rest, I am not using for their intended purpose! I'm using them as rubber feet for various projects, and when ordered in quantities of 10+ and cut in half (2 for the price of 1), they are perfect, and quite cheap. The rubber is firm enough to not squish much with your fingers. It won't skid on most surfaces, either.
Our customers always surprise us with new ways of using stuff. Thanks for letting us know.
