This is a set of 6 Elecom CD/DVD plastic cases (10mm). I purchased a new set of 30, but ended up not using them. (I opened them for the listing, but they were stored unopened.) They are a single-disc storage type with a clear front. All are new and unused. How about using them for storing CDs, DVDs, or Blu-rays? [*Product Details*] Thickness: 10.4mm Media Supported: Blu-ray Disc, DVD, CD Number of Discs per Case: 1 Jacket Storage: Yes Material: Polystyrene Other: Standard type that can store not only index cards but also spine labels. ▲ Although unopened until listed, there are small initial scratches, stains, and dust that are difficult to capture in the images. (Are the manufacturer's quality checks more lenient these days?) I don't think it's very noticeable, but I would appreciate your understanding. (__*) ▲▲ There is a foreign object inside one case. ▲▲ It's a small brown object like in the third image. I tried to remove it, thinking it was trash, but it seems to be mixed in. Would anyone who doesn't mind this be interested? (__*)) Shipping will be via Yu-Packet Post. Bundling is welcome! If they can be shipped together, I can offer a discount (from 150 yen). Thank you very much! ( ˶˙ᵕ˙˶ )
