The Ear Lock Mailer Box is a custom-printed corrugated mailer whose side ear flaps tuck and lock into the walls, giving direct-to-consumer brands a secure closure with no tape and no glue. We manufacture it in the US to your print.
The locking ear tabs hold the box square under stacking and handling, so fragile or higher-value items arrive protected and the box keeps its shape on the doorstep. Assembly is fast because the flaps engage by hand in seconds. An electronics or skincare brand shipping items that need a snug, tamper-evident close benefits from the ear-lock structure over a basic tuck.
