This is a set of 16 MUJI A4 ring binders, a long-selling product. I've been using these for 20 years to store important documents. I've gradually added to my collection, so there's a mix of older and newer ones. I kept them on a bookshelf, but I rarely looked at them, so they're in good condition. Some spines are sun-faded, but the color is dark gray, so it's not very noticeable. Please understand that these are used items. For packaging reasons, this is a set of 16 binders, but I have 66 in total. If you purchase them all together, I will offer a discount, so please consider it.
