When shipping shirts, paperbacks or other light and non-fragile items, why waste money on extra ounces of rigid cardboard? Why not go the softer route and use protective Kraft Mailers? By not using a box, you could end up saving enough on postage to pay for the bag of mailers itself!
These strong envelopes are made in the USA from 28-lb. Kraft paper, highly resistant to tears and punctures from normal use. Inside is a supportive cushion of air bubbles to protect fragile objects from normal mailing stresses. A convenient peel-and-seal adhesive closure ensures the security of your mail. Made in the US from recycled materials with a double-seam for strength and security.
