What can I use A4 postal boxes for?

These postal boxes are perfect for shipping or storing flat and A4-sized items securely (A4 is about 210 x 297 mm). Our boxes are slightly oversized so you have ample room to store and post your goods.

Books, magazines, and documents: A4 postal boxes are excellent for sending books, magazines, brochures, and important documents, preventing them from bending or getting damaged in transit.

Stationery, artwork, and photos: Artists, photographers, and designers can use A4 postal boxes to safely send prints, posters, or artwork without worrying about creases or folds. Notebooks, diaries, planners, folders, and other office supplies also fit neatly into A4 postal boxes, making them great for corporate orders or personal use.

Clothing and accessories: These boxes are also ideal for shipping t-shirts, lightweight jumpers, scarves, and fashion accessories such as belts, ties, and gloves while keeping them neatly folded.

Branded postal boxes

Several of our postage boxes can be branded at Tiny Box Company, with digital printing available in-house. This 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.

So whether you're a business shipping products or an individual sending important items, A4 postal boxes provide a professional, secure, and reliable packaging solution! Want to check out some more options? Find our full range of postal boxes here.
