More Protection Than a Satchel, Cheaper Than a Carton

Satchels bend, envelopes split, and oversized cartons waste postage on empty space. A5 mailing boxes sit in the sweet spot — rigid cardboard protection in a compact format that keeps shipping costs low. Ideal for paperback books, diaries, cosmetics, small electronics, stationery, and accessories shipped via Australia Post or courier.

Fixed Height or Adjustable Height

Fixed-height mailers suit products with a consistent thickness. Adjustable-height mailers feature crease lines at 10mm, 20mm, 30mm, and 40mm — fold to the exact height your product needs and reduce the number of box sizes you keep in stock.

Australian Made & 100% Recyclable

Manufactured in Australia from sustainably sourced paper. 100% recyclable with a minimum 50% recycled content. Ships and stores flat — takes up minimal warehouse space until you need them.
