This black mailing box is great for sending drawing by your children to their grandparents or stationery for a wedding. 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.

Sorry printing is not available on this Black Postal Box.
