Padded Bubble Envelopes 50 x Waterproof Bubble Envelopes for Shipping and Storage (13 x 18 cm, Pink)

Scope of delivery: The size of 50 bubble envelopes is 13 x 18 cm + 4 cm (the height of the seal is 4 cm) and the usable internal size is 13 x 18 cm. They are sufficiently padded to protect fragile items during shipping. Waterproof and moisture-proof: These quilted envelopes have a durable and sturdy surface and the inner layer is a complete bubble film, which is not easy to leak and can effectively shock and pressure. Dual layer protection is safer and effective against dust and water. SELF-SEALING ENVELOP: The padded envelopes have a tamper evident self-adhesive seal. No reinforcing tape is needed, it will only fall off if you tear it off. Once the envelope is sealed, it cannot be opened to protect privacy. PERFECT CUSHIONING PROPERTIES: Unique nylon sealing technology makes the air bubble more durable and provides better protection. The packaging material is a strong 2-ply bubble film that impresses with its extremely high load capacity while being lightweight and flexible. MULTIPLE USE: These small size bubble envelopes can be used in offices, homes, shops, schools and wherever a mailing is needed. And the bubble envelopes are pleasant to the touch and are perfect for writing and stamping
