New .500" wide / 16 gauge x .500" long galvanized staples - original quantity was 10,000 but it appears there is a bar missing. Most of the tag was missing on the box so not sure on the exact brand. Please use the measurements of the staple to verify compatibility with your application. Box has some discoloration and shelf wear but has been stored in dry climate controlled storage.(EBYTRLR-S-2)
