About our box
Tab Lock Mailer Boxes, made to your size
Tab lock mailer boxes close with a tab on the lid that slots into the front panel. It is a simple, secure closure that packs quickly and opens cleanly, and it gives the box a neat front edge for branding.
Why choose our tab Lock Mailer Boxes
A positive locking tab keeps the box closed through rough handling while still letting customers open it easily. It also makes the box reusable for storage or returns.
