I am absolutely impressed with this staple box! I used two thirds of the box in my 18v Ryobi stapler and installed a foil barrier on the underside of the rafters. No stuck or loading issues! Staples load easily and won't jam. The staples in the box were in perfect condition, not a single broken staple. Each staple was a complete, unbreakable staple and loaded easily without breaking in handling. I will be ordering another box before I'm done with this one!
