The Unusual Boxing Glove
The number of people who have used folds even with that can still be counted on the fingers of one boxing glove. Devin's used it a few times and I think Rawls uses a few times but you're right not a lot of people are using itYeah all right so it's an unusual boxing glove here it's got to split down the middle or something It's a Mickey Mouse club it's been out there for a couple of releases and has hardly ever been used.
