Do envelope liners require assembly?

Our liners come attached with a peel and seal adhesive strip for quick and easy assembly. Alternatively, we also provide assembly services for a fee. Simply select the required service, and the price of liner and assembly services will be reflected. Do note our envelope liners are designed and die-cut to fit our A7 (135mm X 185mm) envelopes. We cannot guarantee these liners will fit envelopes purchased outside of Papertuity’s website.
