Common questions
What size items fit in a 14 1/2" x 8 1/2" #3 mailer?
The #3 size accommodates items up to 14 1/2" long and 8 1/2" wide, including folded clothing, small books, jewelry boxes, phone cases, and documents. The 3/16" bubble lining compresses slightly to fit moderately thicker items without straining the seals.
Are these mailers UPS and USPS eligible?
Yes. At 8 1/2" x 14 1/2", these mailers fall within standard parcel dimensions for both UPS and USPS, avoiding oversized surcharges. The lightweight kraft construction helps minimize dimensional weight penalties.
How effective is 3/16" bubble for fragile protection?
3/16" bubble cells provide adequate shock absorption for moderately fragile items like ceramics, glassware, and electronics. For extremely delicate or high-value goods, pair these mailers with additional internal cushioning materials like foam sheets or air pillows.
Can the self-seal closure be resealed or adjusted?
The peel-and-stick closure is designed for single-use sealing to maintain tamper-evident integrity. Once sealed, the mailer cannot be repositioned without visible damage, ensuring customer confidence in product authenticity and security.
