Review (3/5): Looks like I got the "Bad Kind"
Apparently there are two types of these sponges: One that is a bit more dense, whiter, and cuts easily, and then there's one that has bigger holes, is slightly more yellow, and crumbles more easily. I got the second kind and I am not as happy as I could be. They are dirt cheap so I guess I'll still use them, but if I need to order more, I will try to get the other kind. Thanks Sir Wappel!
