A sustainable oversize A5 postal box, able to be sent as Royal Mail `large letter’. Our boxes are manufactured in Dorset using biodegradable FSC accredited corrugated board. A noticeably stronger box than most, using 200K/200T rather than lower grade imported material. Product protection combined with a perfectly flat, smooth surface on which to add branding.
