These pleated top boxes feature a top flap that folds down and tucks in. The flap tucks securely into the front panel of the box. Two flaps fold over each other and tuck into side slots. Some styles have a tray-like base with an attached locking top. The top can open for display or close for shelving. Straight tuck end and reverse tuck styles are both available. A treasure chest style opening is offered on select designs. These boxes are built as a simple one-piece construction.
