Before buying any storage box, you need to know how much you need for all the items you need to keep. Put all your stuff in one room, and arrange according to what happens together in a box. Put all the books, shirts, shoes and hats together. Then for each per “category”. Like, all formal shoes are put together as well as all the underwear and all the extra dishes you might not use for another year or two. Doing this will help you get the right amount of boxes you need, and will save you extra spending money that might end up as part of the chaos.
