Rapid K1 pliers stapler comes with 5 year warranty IF you use their staples

Excellent staples for the Rapid Classic K1 Plier Stapler (90119) I also bought .

I use these staples with my Rapid K1 Retro Classic Stapling Pliers

it is the only staple that works in Rapid Stapling Pliers K1 90119, no other 5/16 works in that plier
