Our Large Parcel Sized Cardboard Envelopes are perfect for mailing large flat items such as prints or photographs. These envelopes are crafted from extra robust E-flute corrugated card, and follow the size regulations for large parcels set by the Royal Mail. They feature a time-saving peel and seal adhesive strip which provides secure closure without need for extra tape, which combined with the large opening and pre-creased folds makes them quick and simple to pack.
