A sustainable oversize A4 postal carton, able to be sent as Royal Mail `large letter’. Our boxes are manufactured in Dorset using only 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.
