These come 3 to a box, the base is ABS black plastic. One of mine had a hole in it about the size of nail. These plastic base's are filled with some kind of sand and Iron Fillings and some had spilled out. Rather than return them, I just put a screw in the hole and wrapped it with tape around the base. Over all I think these are OK. The plastic storage box they come in is like really, really Cheezy and cheap.
