Cardboard Book Mailers With Crush Zone Protection

The ends of each mailer extend beyond the contents to create a built-in buffer zone. Rough handling from couriers and postal networks hits the crush zone first, not your book. The result — fewer damaged spines, fewer creased covers, fewer returns.

Fixed Height or Adjustable Height Book Mailers

Fixed-height mailers suit consistent book thicknesses — one book, one clean fit. Adjustable-height mailers feature crease lines at 10mm, 20mm, 30mm, and 40mm — one box fits paperbacks through thick hardcovers, so you keep fewer sizes in stock and pack faster.

Australian Made & 100% Recyclable

Manufactured in Australia from sustainably sourced paper. 100% recyclable with a minimum 50% recycled content. Your customer drops the mailer straight in the recycling bin.
