Sparco Size 4 Bubble Mailers

These mailers are designed for shipping small to medium items that need cushioning during transit. The pack contains 100 envelopes suited for e-commerce sellers, office dispatch, or personal mailing needs.

Self-seal Kraft construction

Each envelope uses a durable Kraft exterior with interior bubble cushioning to protect contents from impact. The self-sealing closure removes the need for tape, glue or water, speeding up the packing process.

Replaces plain paper envelopes

The padded design upgrades shipments where items previously arrived bent or scratched. The jump is worth it when breakage costs or return rates outweigh the slight increase in envelope weight.
