Ingredient Composition: Choose gluten free rice paper sheets with a combination of rice flour and tapioca flour in the ingredient list for enhanced durability. Visual Inspection: Avoid wrappers that are broken, cracked, or do not lie flat, as these signs may indicate exposure to moisture. Check Expiration Date: While checking the expiration date is wise, keep in mind that properly stored wrappers last a long time. For example, our wrappers have a shelf life of 2 years from the manufacturing date.
