Frequently Asked Questions

What is the difference between board-back and standard envelopes?
Board-back envelopes have a rigid card or board lining on the rear panel, preventing the envelope from flexing or bending during transit. This makes them suitable for photographs, certificates, prints and artwork where crease or bend marks would be unacceptable. Standard envelopes have no board backing and should not be used for bend-sensitive contents.
