This is a 30-count pack of If You Care sandwich bags. Since they have been handled by someone else, I don't recommend putting food directly in them.＾＾； I use them as junk journal materials and pockets. They are thin, slightly crisp bags, perfect for paper lovers♪ Size: Approximately 20 x 16 cm, with a gusset of up to 5 cm. Sandwich bags made from unbleached pulp of Nordic spruce. They are oil-resistant and ideal for nuts, potato chips, cookies, butter, mayonnaise, and sandwiches with oil. They are also suitable for microwave use. They are uncoated, so they do not contain petroleum-based paraffin wax, soy, or other waxes. Like other paper products, these snack and sandwich bags are completely chlorine-free... From the website.
