Inefficient storage
Firstly, lego has designed a connectable storage solution where you buy different large bricks and stack them. Some have drawers, some don't; some large large boxes (like this), some are smaller boxes (ie half the size). I think all of that is great. If you are after a very large scale storage solution and intend to buy loads of these, you will love them. However, if you are after a practical solution for a volume of lego that will fit eg a small bin then you will most likely be looking for the best volume of storage, as I was. I saw these in the London store and you can't open them to see inside. The way they are packaged is that the wrapping card goes all the way around, so you can't see inside or underneath the box. The underneath is also not photographed on the site. This is unfortunate as, I think, the dimensions stated are not relevant to the storage volume these offer. The floor of the box is raised inside, so about 20% of the box's storage volume is lost. Then. you have the 8 bumps at the top, which are empty inside and cannot be use for storage. So, all in all, you lose a large amount of storage space to this stackable feature. If that's your thing, fine. If not, these boxes offer really poor storage volume. I have attached pictures showing the bottom and the top of the box. Finally, inside, the bottom has a small crevices which means that 1x1 pieces will get stuck down there and have to be removed by a flat screwdriver. They can't be removed with fingers or by children. I think the stackable feature is great but I cannot understand why such a poor design was used for the floor, which gets parts stuck and the storage generally. Unless you want to use these primarily for decoration then I would not recommend these for storage at all. There are many better options for storing lego which waste far less space.
