Buying guide

How to Specify a Custom Mailer Box

1. Confirm the internal size

Measure the packed product, including tissue, insert and protective wrap. Share the internal length, width and height so we can prepare the dieline around the actual fit.

2. Select protection and flute

E-flute suits lighter retail mailers and fine print; B- or C-flute provides more cushioning for larger shipments. Our materials guide explains the main flute options, and we can recommend a board grade after reviewing product weight and transit conditions.

3. Choose the brand experience

Specify outside and inside print, tear strip, inserts, coating and closure style. For subscription and DTC programs, flat-packed construction helps reduce storage volume while the printed interior creates a stronger unboxing moment.

4. Confirm the landed shipping plan

Your quote can compare FOB and DDP options. See our FOB vs DDP guide for the responsibility split. Final shipping cost depends on carton dimensions, order quantity, destination and timing; we confirm these details before production.
