This is my JEDI threaded and stackable coaster set. The main features of this model are that they are stackable by threading into one another. You can stack as many as you want.

The second feature of this is there is a "bottom" container for keeping things safe. There is also a threaded bottom that allows you to made as many containers as you like.

Please do not sell any of my models commercially; if you wish to do this, you need to join my Patreon or here on Thangs.
