Here is an unopened case of 100 #4 (9.5″ x 14.5″) Poly Mailers. Each mailer has 9″ x 13.5″ of usable space inside and a self-seal closure. Most cases will have the sticker shown in the 3rd and 4th pictures, not the 2nd picture. If you can pick these up in zip code 60438, my cost will be reduced significantly, and I am happy to credit the savings back to you. (My cost to ship to you is usually more than half of my asking price)
