Common questions

What ECT rating does this mailer have and why does it matter?
ECT-32-B provides 32 ECT (Edge Crush Test) strength, ideal for protecting lightweight items during shipping. This rating balances crush resistance with cost efficiency, strong enough for fragile goods without overengineering for heavier products.
How quickly can my team assemble these mailers?
One-piece fold-and-tuck design requires no tape, glue, or staples. Team members can assemble boxes in seconds, reducing fulfillment labor by 40-60% compared to traditional setup-style boxes.
Will these mailers reduce my postage costs?
Yes. Lightweight corrugated construction minimizes dimensional weight charges on USPS, UPS, and FedEx parcel services. For high-volume shippers, switching to these mailers typically reduces per-unit shipping costs by 15-25%.
Are these mailers suitable for fragile items?
Yes. Double-wall crush-resistant design on front and sides protects fragile items like electronics, cosmetics, and glassware. The 4" x 3" x 2" size is optimized for small fragile packages that require extra protection without excess void fill.
