Last month we found these for sale in Disneyland but could not for our lives figure out what they were supposed to be or do. Since there was no packaing, title, or instructions it seemed it must be something that would be pretty obvious to the masses, but we remained dumbfounded. At last, during this last trip my father had a stroke of brilliance and realized they were stoppers for a wine bottle! It made perfect sene after that, of course the cork would expand and be unuseable after opening but I, being raised in an home where neither my parents nor thier parents consumed any sort of alcohol, had to think through the thing rather than simply identify it.
