What can I use A6 postal boxes for?

These postal boxes are slightly oversized to fit A6-sized products (which measure around 105mm x 148mm), making them ideal for shipping and protecting small, delicate items while keeping postage costs low. Their compact size makes them perfect for e-commerce businesses, gift packaging, and secure mailing...

Cards, invitations, and small documents: A6 postal boxes are great for sending postcards, greeting cards, wedding invitations, or business cards, ensuring they stay flat and pristine. A6 postal boxes also provide excellent protection for small prints, sticker sets, cards, and polaroid-style photos.

Jewellery and accessories: Our postal boxes for A6 are also perfect for shipping rings, earrings, necklaces, bracelets, cufflinks, and watches while keeping them safe from scratches and damage. Also use them for packaging small cosmetics like lipsticks, essential oils, or sample-sized skincare products.

Crafts and tech accessories: A6 boxes are ideal for craft businesses shipping handmade keychains, resin art, badges, wax melts, or small candles. They’re also perfect for compact electronics like USBs, memory cards, phone accessories, or earbuds.

Branded postal boxes

Several of our postage boxes can be branded at Tiny Box Company, with digital printing available in-house. This process involves applying a digital-based image to a box using UV ink - so why not add your own logo, message, or image? Alternatively, opt for a branded sticker to liven up otherwise plain packaging.

Postal packaging solutions

At Tiny Box Company we also have several postal bags - from padded postal bags and recycled cardboard envelopes to 100% compostable mailing bags. Shop our full range for a complete postal packaging solution, with a wide selection of items to pack like tape and stickers.

A6 postal boxes are the perfect choice for small, valuable items, providing a secure and professional packaging solution. Want to check out some more options? Find our full range of postal boxes here.
