These Staples Work Great I must have fired over 100,000 of these staples using the Porter-Cable US58 1/4" to 5/8" 22-Gauge C-Crown Upholstery Stapler. I use them to attach rugs to wood for a carpeted cat wall shelf. The staples come in a very well packed box and have never received a box with a broken row of staples. The staples never stick and hold so well that I'm always afraid to pull them out for whatever reason.
