eBay Shipping Supplies 9.5″ x 13.25″ This item is brand new. Let me know if you have any questions. These mailers are lightweight, which helps to save on postage. They are also recyclable, moisture resistance, and very durable. They have a self seal closure on them so no need for tape, and they have a tear strip for opening so the contents don’t get damaged while opening. Thanks you so much for viewing!
