Staples Poly Mailers Plastic Ship Bag 16×16 Over 400 Originally was a 500 poly bag box. There’s three complete bundles containing 125 each and a healthy stack of extra ones from the same pack. The whole 500 poly bag pack had four bundles of 125 so it’s mostly complete. If I had to guess I would say that the opened bundle has at least 80 bags there still but definitely maybe more. I’m also throwing in 15 extra 20×14 poly bags. Originally paid $140 for the 500 poly bag set from Staples FREE SHIPPING
