I was looking for cases to organize my kitchen after I moved house and changed my kitchen, but I found these expandable cases to be perfect for me, as I didn't want to measure the dimensions to make sure they fit perfectly or fit the cases together like a puzzle. I bought it thinking that I would just consider the width for now and adjust the depth later, and then combine it with cases from 100 yen stores and the like, but just using this case made it look neater and I was able to organize things by type, and I was able to store small things like plastic wrap and Ziploc bags in the 100 yen store cases on the front side! I think I'll buy a shallow type for the bathroom storage.
