This black postal box is great for sending gifts or care packages out to family and relatives. Why not send some drawings from the kids, or any craft projects they've been working on? This size box is also ideal as a subscription box for your business. No fuss and easy shipping as this box is accepted by Royal Mail. The box is easy to assemble and secure enough without the need for tape, although why not personlise it with a printed label for added strength and security?
The boxes are single walled and made from corrugated card.
The box can be used as a snacks delivery box for small baked treats.
