For your consideration, here is a Box of Stanley Bostitch 3/8 Inch Heavy Duty Staples, no. SB35 3/8-5M. It was a 5,000 count staple box. It is mostly filled. I'd estimate it at least 95 percent full. The box has some wear on it. Item pictured is the actual item up for sale and comes from a non-smoking household. (360.766x-.15hc)

For use with the following models:

Stanley Bostitch B300HDS

Stanley Bostitch B320HDS-FC
