Frequently Asked Questions
Q: What size items fit in these 18×23 cm bubble mailers?
A: The 18×23 cm interior comfortably fits small-to-medium items such as jewelry, cosmetics, folded clothing accessories, small books, greeting cards, seeds, and similar lightweight products up to roughly 17×21 cm once the bubble lining is accounted for.
Q: Are these bubble mailers waterproof?
A: Yes — the multi-layered polyethylene (plastic) construction provides excellent moisture resistance, helping to keep contents dry even in rainy or damp shipping conditions.
Q: Can I write or print addresses directly on the mailer?
A: Absolutely. The smooth laminated outer surface is compatible with permanent markers, ballpoint pens, and self-adhesive printed shipping labels, making addressing quick and neat.
Q: Is the self-seal closure reusable?
A: No — these mailers feature a tamper-evident peel-and-seal strip designed for a single, secure closure. Once sealed, any attempt to open the envelope will leave visible evidence of tampering, ensuring package integrity for your recipients.
