These oversized Quality Park poly mailers are perfect for shipping soft and non fragile items. The tear-resistant poly keeps your shipments protected from rain, snow and wear and tear from truck, train and airplane transit. Provide light and less fragile items with extra protection from the elements when shipped. Add some personality to packages and stand out with color. Pack up goods from home or your small business, then simply peel off the Redi-Strip adhesive strip and seal closed. No moisture is needed, so these envelopes are a clean, sanitary choice. Each mailing envelope has anti-tear tape, so it's harder to tamper with once sealed, plus they are lined to conceal what's inside your shipments. When ordering shipping supplies, stock up on these 10 inch x 13 inch lightweight poly mailers and save on shipping. Box of 100 pink 10 x 13 shipping envelopes.
