Multi-height Mailers

Adjustable-height cardboard mailing boxes with multiple crease lines — one box fits four different product thicknesses. Fold to 10mm, 20mm, 30mm, or 40mm internal height depending on what you’re shipping. Buy multi-height mailers online — Australian made with delivery Australia-wide.

One Box, Four Heights

Pre-scored crease lines let you fold each mailer to the exact height your product needs. Books, documents, clothing, cosmetics, electronics accessories — whatever you’re posting, adjust the box to fit rather than padding out a box that’s too deep.

Less Waste, Cheaper Postage

A box that fits the product closely means less packing material, lower freight charges, and a cleaner unboxing experience for your customer. No more half-empty cartons stuffed with paper.

Australian Made & 100% Recyclable

Manufactured in Australia from sustainably sourced paper. 100% recyclable with a minimum 50% recycled content.
