I have 60 of these Disc Box CD jewel box holders. Each Disc Box will hold 10 CD's. They slide together on the sides and top to bottom. 60 Disc Box x 10 = capable of 600 CD's. The CD's in the photo are for illustration purposes only and are not included. I think I paid about $3.50 each for these years ago so that would be about $210. worth so $20 is a bargain for these.
