Flap boxes close by folding rather than by taping, which is why they suit anything that gets packed by hand at volume. We build them in corrugated boxes for shipping, paperboard for retail, and rigid board where the box needs to feel expensive. Add a fitted insert and the same box works for ecommerce despatch, shelf display, gifting or document storage. Low-MOQ runs mean a boutique brand and a national retailer can order the same structure.
