World Centric's 13" x 13" Unbleached Lunch Napkins are made from wheat straw fiber, which is derived from the stalks of wheat plants (no protein, gluten, or allergens, which are contained in the grain of wheat). They're unbleached, preventing toxic dioxins from entering the environment and food chain, and easily compostable in industrial facilities or at home. Whether you're packing lunches to-go or setting the dinner table, Unbleached Napkins make cleanup (and clean hands!) a little easier and help prevent the use of paper napkins derived from virgin wood pulp.
