I used these to store dried fruits, rice, pasta, and other dried goods. I've used them for about four years, so there are stains that won't come off, tape residue, and clouding on the lids. They were in use until recently, so they are still usable, but please refrain from purchasing if you are concerned. This is a set of three empty containers, but I can increase the number to 13. If you want to add more, I can sell them for an additional 300 yen per container, so please inquire before purchasing if you would like to increase the quantity.
