Flexibility & protection are at the core of this extremely useful coupling. Simply use the envelope as it is for A5 size items or combine it with our rigid C5 / A5 stiffener to create an envelope that will outperform board backed envelopes and safeguard those important documents that must not be bent in the post.

Simply & very quickly inserted, these fluted stiffeners will instantly transform a C5 A5 paper envelope into a robust, highly effective board backed envelope alternative & provide greater rigidity than any board backed or hard backed envelope on the market.
