The CD Vault looks like a boxed set of 6 CDs, but it contains a secret storage compartment to secure small valuables from burglars and prying eyes. Blends perfectly into a CD collection. It's a great way to securely hide things, especially since CDs are no longer of any interest or value to burglars. The CD Vault has a felt-lined compartment and lid. Compartment size:  4" x 3.75" x 1.5". Titles may vary.
