Bags are thin cotton for grocery/other shopping/ everyday use. 15"W x 16"H, made of 100% 5oz natural cotton, lock stitching inside, with compacted stitching throughout, including cross-stitching at the handles for maximum strength allowing the bag to hold up extra bearing capacity. With two reinforced handles sized 1"W x 25"L, convenient to carry in hand or wear on your shoulder, sturdy enough for all kinds of daily use. Do not machine wash. Bags will shrink at least 10% of original size. Vinyl has a matte finish, is heat sealed, and will stretch without cracking.
