- Avoid bubble mailers for fragile/rigid items; use a box instead
- Buy in bulk (100-packs) to cut per-unit cost significantly
Frequently Asked Questions
What size bubble mailer is best for eBay?
For most small items, a #0 (6×10″) or #2 (8.5×12″) covers phone cases, cosmetics, books and small apparel. Pick the smallest size that fits to keep postage cheap.
Are bubble mailers waterproof?
Poly bubble mailers are water-resistant and protect contents from rain; paper kraft mailers are not, so choose poly for apparel and moisture-sensitive items.
Can I ship fragile items in a bubble mailer?
Only lightly padded, non-rigid items. For anything breakable or rigid, use a box with proper cushioning instead.
