Postal Boxes - Recyclable, Sustainable & Ready to Mail

At Tiny Box Company, we offer a wide range of postal boxes and mailing boxes for everything from personal parcels to high-volume business orders. Our collection includes flat pack and rigid styles in sizes including A6, A5, and A4 - including Royal Mail large letter boxes.

Made from eco-friendly materials like corrugated cardboard, our boxes are strong, secure, and sustainable - ideal for eco-conscious individuals and businesses alike. Use them to ship everything from photographs and stationery to artwork, gifts, or corporate brochures.

What's corrugated cardboard? Quite simply, it's made up of three layers of board - two sheets covering the outside and one in the middle that has a rippled shape. This is what makes it so strong, which is why it's often used for mailing!

Read more here on selecting the perfect material for your gift/postal boxes.

Brighten up your packaging with colourful A6 mailing boxes or go classic with kraft brown and white finishes. For delicate items like books or flowers, explore our kraft mailers and flower letterboxes with circular hole cutouts.

They’re not just for shipping - our boxes are also great for storage, gift presentation, or keeping handmade items protected. And when space is limited, our flat pack options fold down neatly. Need some help choosing the right postal box for your business? Check out our guide here!

Add your logo with digital printing to make a lasting impression. Whether you need a few or are ordering in wholesale quantities, we offer flexible options for every business size.

Finish the look with our eco-friendly postal bags, kraft tape, shredded paper filler, and more packaging accessories - all designed to keep your products safe and stylish.
