Common questions
What is the #2 size and will it fit my products?
The #2 mailer measures 8.5" wide by 12" tall (interior dimensions), making it ideal for items up to roughly 10" x 6" or smaller. Common fits include folded clothing, small electronics, jewelry boxes, and document packs. Measure your product against these dimensions before ordering to ensure proper fit and protection.
How much cushioning protection does the 3/16" bubble provide?
The 3/16" bubble lining delivers mid-tier shock absorption suitable for fragile items requiring basic protection during shipping and handling. For heavier, more delicate items (glass, ceramics), consider upgrading to larger bubble cell sizes or supplementing with additional internal padding.
Are these mailers UPS-eligible and what are the shipping weight implications?
These lightweight kraft mailers keep dimensional weight low, reducing UPS, FedEx, and USPS surcharges. Each empty mailer weighs approximately 0.3 oz, adding negligible cost to small item shipments, critical for e-commerce margin protection on low-value orders.
Can I apply shipping labels directly to these mailers?
Yes. The kraft paper exterior accepts standard thermal and inkjet labels cleanly, and the flat surface provides ideal label adhesion. The tear strip does not interfere with label placement when positioned in the upper portion of the mailer.
