What are brown boxes made from?

We use strong, high-quality kraft corrugated cardboard to make our brown boxes. They’re tough, durable, and designed to protect your products from packing to delivery.

I run a small business—can I order in smaller quantities?

Definitely. We work with businesses of all sizes and offer flexible quantities, so whether you need a small batch or a bulk run, we’ve got you covered.

Are they suitable for shipping fragile items?

Yes—when paired with the right internal packaging (like void fill or cushioning), our brown boxes are perfect for shipping fragile or valuable goods safely.

How quickly can I get my order?

We offer next-day dispatch on standard sizes and just a five-day turnaround for custom orders. No long waits, no stress—just quality packaging delivered fast.

Are your brown boxes eco-friendly?

They are! We make our boxes using recyclable materials and incorporate recycled content in every design. They’re also reusable and sourced from responsibly managed forests—so you can pack with confidence and a clear conscience.
