Invitation boxes use folding cartons with three tab locks on the top lid. These flaps tuck into holes, closing the box without adhesive. Cherry locks, also called friction or snap locks, feature two ear-shaped flaps. A Roll End Tray, or walker lock tray, folds over the side walls securely. Small tabs fit into slots for closure without any glue. Rigid construction maintains shape and prevents bending during handling. Covered presentation boxes hold invitation cards, envelopes, and inserts neatly. This structure keeps every suite piece aligned for elegant unboxing.
