These #3 white self-seal padded mailers measure 8 1/2 x 14 1/2 inches and feature an integrated fiber padding interior that expands during transit to absorb shock and protect contents without requiring added cushioning material. The peel-and-seal closure uses a natural rubber adhesive that bonds only to itself, forming a secure, tamper-resistant seal with no tape or heat-sealing equipment needed.

The moisture-resistant and puncture-resistant outer shell makes these mailers a reliable choice for e-commerce fulfillment, retail distribution, subscription box operations, and manufacturing environments shipping lightweight or fragile goods. The self-seal format supports faster pack-out workflows by eliminating extra sealing steps at the packing station.

The white exterior presents a clean, professional appearance suited to both direct-to-consumer and B2B shipments. Each case contains 100 mailers and ships via parcel carrier.
