Looking for t-shirt mailers? Our SL3 mailbox range of slim mailers are absolutely perfect for mailing t-shirts and other fashion items, A4 sized magazines, documents, photograpics and artwork. This mailing box features our market-leading hot melt peel’n’seal / red-tear-strip combination, thick and strong corrugated cardboard material, and 100% green recyclable credentials. Beware of pale imitations and cheap, ‘clipfast-tray’ style A4 packaging size boxes.

The strong design of this slim mail box is doormat friendly and can withstand a good bashing.

Hinged lid for extra wow factor, with secure seal. Hot melt adhesive gives the best, tight seal – at least twice the strength of standard double-sided tape.

Environmentally friendly, 100% recyclable.
