I recently started buying books from book depository myself. Largely, I've been storing everything in a vinyl disc case... which is now full of FAKKU book and artist boxes. Honestly, I want to find something else to start storing my book in, but I'm working with limited space; realistically only have space left on top of a bookcase, so the contain would need to be the right dimensions to fit.
At one point I was considering some of the
Iseto Bunko containers from Japan but the shipping is kinda of high.
