These large blank A4 size labelopes are excellent enclosed envelopes. They are a larger envelope to ensure your delivery address is really noticed!! They are a very economical and fast way of securing your documentation to the goods you are dispatching. This purchase is for a lot of 100 A4 sized envelopes. Please note the entire envelope is A4 size so once the corners are sealed it will not quite fit an A4 sheet in it but ideal for a larger print size in any case. The envelopes have a self adhesive backing which is simply peeled off and attached to the parcel.
