Our boxes have a capacity of 67 litres. The dimensions are: 35cm wide x 55cm length x 35cm high. Since it isn’t always easy to estimate the number of boxes needed, simply order a few more. We will only charge you for the boxes you use. An average box will hold 80 T-Shirts or 12 File Binders. Got something that won't fit in our boxes or have your own boxes? We can store suitcases, larger items like ski equipment or already boxed items for just £9 per item.
