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 brand 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. ▲ They were unopened until listed, but there may be small initial scratches, dirt, or 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. (__*) Shipping will be via Yu-Packet Post. Bundling is welcome! Discounts are available if items can be shipped together (from 150 yen). Thank you very much! ( ˶˙ᵕ˙˶ )
