Be confident when you ship your products with Royal Mail.
We’re a big fan of custom made boxes. But, when you’re sending via Royal Mail, you want certainty that you order the right dimensions. That’s why we’ve restricted the sizes on this page to match. So, you can send your next novel, the latest earphones, or your new t-shirt design without worrying about underpaying. Just make sure your parcel weighs under 2kg.
Great for:
- Books
- Clothing (like t-shirts, underwear, and trousers)
- Small tech
- Trainers and shoes
