do not know for sure as box is unopened they may work great but they could be too thin and a failure for my use! i purchased because i had none in home and will need some in February so until then they make a good paper weight holing some mail items to be sent out
Don’t waste your money I thought a staple was a staple wow was I wrong ! They break off and have gotten stuck in 3 of my 4 staplers ! I lesson well learned !
