At StorageCollect we take our storage boxes seriously. Our storage boxes are specially designed to withstand 30kg load, repeated handling, and if need be, overseas shipping:
Our boxes' flaps don't just meet in the middle - they overlap! They make it almost impossible for the bottom to give way.
Our boxes are made from export grade stitched double-walled cardboard weighing 300g per square metre. You won't find anything like them at your local self storage or other retailers.
