The Mono Carton Boxes are made of corrugated cardboard, lightweight but sturdy, which are great for mailing small items. Our boxes are flexible and good in buffering, which can greatly offset impact and pressure. The shipping boxes are excellent for gift giving or packing for small businesses, especially when they are embellished with labels, stickers, and ribbons. These are easy to put together in seconds, the tuck top has two locking taps to closure boxes and keeps secure. In addition, these Mono Carton Boxes can also be reused.
