Our side lock 6 corner boxes feature four regular sides overall. They can be shaped into rectangles or squares as needed. Six locking cuts on the two larger sides form the lock. Two side flaps tuck in to close the box securely. This self-lock system means no extra tape is needed.
These boxes ship flat and assemble easily into their original shape. Choose deeper or shallow styles depending on the product size. Pre-glued sides and extra flaps create a tamper-resistant closure.
