Lock Bottom Cartons, Color : Brown

A "lock bottom carton," also called a "1-2-3 bottom box" or "snap-lock bottom box," is a type of folding carton where the bottom flaps interlock with each other, creating a very secure and sturdy base, making it ideal for holding heavier items compared to a standard tuck-end box; essentially, the bottom "locks" into place when assembled, providing extra strength and stability.
