I've been making these for over a year, they're actually an older invention than the pet rocks. My sisters and practically all of their friends have one sitting in the dashboard of their cars. We call them Tom-stones, which is likely the worst name ever, but it stuck. The first one I ever made was gray and looked kinda like a tombstone...hence "Tom-stone." I hope that's not too morbid for everyone! :D
This here is a whole bunch of them, they fit nicely together! Someone said they look kind of like dominoes...I guess they're right about that!
Now available in my
Etsy shop. :)
