One case of 50 keychains. Back by popular demand is the Hughes Wave Motion Machines "WaveChain" Keychain. I have not produced these since 2012 when they were a hit with adults and kids alike. Gently tilt the 4?x 1? x .66? mini vessel from side to side and watch the cool wave patterns form. Kids and adults alike love them! These make great little stocking stuffers, as well. Comes gift wrapped in clear cellophane with a shiny gold twisty tie to dress it up. The side of the keychain has my website printed on it in case you'd ever like to purchase a custom 22" "Model One" Wave Motion Machine or more WaveChains. Buy more and save! Please message me for Bulk pricing. I have 300+ individual pieces available.
