Here's a way to do your part in eliminating the use of plastic bags. These eco friendly, stylish, and resuable snack bags made with cotton fabric on the outside and a food safe, baby safe, and hospital grade PUL lining on the inside with a plastic snap closure are just what you need to replace those zip lock bags. This is a set of 4 snack bags (1 lg, 2 med, and 1 sm.) you can use to store your leftovers or carry your sandwich or snacks in. They are very durable, washable and can be used to hold a wide variety of different food items. The large bag can hold a sandwich, slice of pizza, breakfast sandwich, left over hot dogs, etc., the medium bag is great for leftover onions, peppers, baked potato, raw veggies, cookies, brownies, crackers, grapes and more, the small size is perfect for a boiled egg, leftover garlic cloves, raisins, small portions of snacks and so much more. These can also be used for pet treats and fresh herbs. Please note that these bags are best for short term food storage for most items (about 2-4 days). These snack bags can be washed in warm or cold water and dried on low to medium heat in dryer. They launder exceptionally well and will give you years of use when taken care of properly. Measurements for each size are approximate. Trim, PUL lining, and snap colors may vary from what is pictured. Large - 6"x7" Medium - 5"x5 1/2 Small - 4"x4 1/4"
