Blake Board Backed Envelopes
Here at Office Stationery we have a great range of Board Backed Envelopes. Board Backed Envelopes are great for sending important documents including certificates, as they offer a hard back, ensuring extra protection. They also are commonly known as Do Not Bend Envelopes as they are normally printed with Please Do Not Bend on the front.
These Board Backed Envelopes are available in A4 (C4), A3 (C3), A5 (C5), as well as a whole variety of sizes to suit your needs. All of our Board Backed Envelopes have a peel and seal closure to them which gives them a longer shelf life. Our range of envelopes come from top brands, including 5-Star, New Guardian, Q-Connect, Plus Fabric and more, giving you top quality each and every time.
If you cannot find the Board Backed Envelopes you are looking for or have any questions regarding any of our products then why not call our friendly UK team, they are always happy to answer any questions or help you in your search.
