Rigid Envelope Mailer - A5 Bundle (Pack of 25 QTY)

Designed to fit through nearly any standard letterbox for reducing postage rates, and made from protective corrugated cardboard to offer greater protection than standard paper envelopes or padded bags, our rigid mailer range is suitable for small letters, jewellery, small item orders and other rigid media. These do not require tape to assemble, however it is recommended to use clear adhesive tape to secure tampering in transit.
