@polychrome okay but serious question i’ve wondered about since first seeing these in college: how do you ship these to the origination point in a way that they’re not pre-ruined?
@r4v5 @polychrome There is a backing on the product that must be removed before the balls can move (the balls probably start stuck to those red dots). Removing the backing also exposes the adhesive used to affix it to a package.
@r4v5 great now I'm not going to sleep tonight.
Could email the company and ask!
