I can think of a couple people from past gaming groups I would want to buy these. You know the "I pick up my dice immediately after I roll them and always seem to get at least a sixteen" guy.
I had a player at a game store that would roll his dice behind his GIANT BUCKET mug. He got so very man cirts. One of the few times I'd run with a DM screen...... tought to me by another DM at those games.
