#4 white self-seal padded mailers offer a 9 3/8 x 13 1/4 inch interior cavity lined with fiber cushioning that expands under handling pressure to absorb shock and protect contents in transit — no supplemental padding required.

Well-suited for e-commerce fulfillment, publishing houses, apparel brands, and retail distributors, these mailers handle documents, soft goods, literature packs, and lightweight products that need reliable cushioned protection without a rigid corrugated box.

The outer shell resists moisture and puncture damage through standard parcel handling. The peel-and-seal closure uses a natural rubber adhesive that bonds to itself, requiring no tape. Each pack contains 25 mailers and ships via parcel carrier.
