Burning CDs or need to repackage a music collection? This bulk pack of 100 standard black CD jewel cases is exactly what you need. They're the classic, familiar case: a 3-piece design (front cover, back cover with clear spine, and a removable inner tray) that holds one CD and a booklet/insert (up to 32 pages). They're heavyweight at 90 grams each, made from warp-resistant polystyrene, so they're more durable than flimsy cheap cases. The spine is the standard 10.4mm thickness. They have a professional, clean look perfect for musicians, bands, studios, or anyone archiving CDs. USDISC assembles them in the USA. Dimensions are about 5.0\ x 5.67\ x 0.4\. A reliable, no-fuss solution for CD packaging that looks and feels solid.
