Lewtemi 2 Pieces Bowling Rosin Grip Bag Powder Bowling Grip Sack for Drying Hands Golf Accessories, Black

Work like it should.

Had to physically throw it against the wall to get even the smallest amount of resin out. Don't waste your money .

These sacks and great for getting the grease off of your fingers before you bowl.

ok, but could be tackier

If you don't mind a little rosin powder around while you're bowling (on your clothes, on the table) then this is the rosin bag for you. I like it because this one releases just the right amount of rosin powder to absorb hand moisture and add tackiness with minimal mess.
