These 135 x 93 x 45 mm boxes are part of our 0426 range. This means they are held together without tape - simply slot the flat net together when you receive it. They work perfectly for posting a wide range of smaller products, especially those that need to lay flat in transit.

Try our cardboard box size guide for more information about measuring your items and finding the box that's right for you.

You don’t have to stick to the boxes in this range if you can’t find what you’re looking for. Explore our other cardboard boxes (0201 and 0427 styles are available), or use our box calculator to get quotes for your own 0201, 0203 or 0411 bespoke box. Box printing services are also available, allowing you to add your logo or other individualisation to your boxes.

Boxtopia is committed to delivering your boxes as quickly as possible. It usually takes just a few days to make boxes from our stock board although, subject to workload, we can often supply products on a next day delivery if necessary. For larger quantities of boxes, it is more cost effective for us to buy the board in cut to size so that we can make the boxes without any waste material. Typically, we can despatch these within a week. If you have a deadline, just check with us first.
