I was worried after reading the other review that you would need the Sentry sleeves to store DVD's, but after looking at the specs and measuring my DVD's in their case I could tell that the sleeves were not needed. I do family video editing on a computer in another room and wanted to store the finished DVD's near the living room DVD player in a safe but easy to access way. The front nob turns to secure the safe closed without requiring me to lock it shut. DVD's or CD's in their standard jewel case fit inside the safe with the plastic tray inside.

I did notice that Sentry does sell more sleeves on their own website, but I don't have that many to store yet.

THIS SAFE IS DESIGNED TO STORE CD/DVD'S. IT COME WITH 10 SLEEVES. SPEC'S SAY IT WILL HOLD UP TO 100 CD'S. COMES WITH 10 SLEEVES. SENTRY DOES NOT SELL THE EXTRA SLEEVES. WHEN SENTRY IS CONTACTED THEY WILL SEND YOU TO AN OFFICE SUPPLY STORE. SENTRY WILL NOT TELL YOU WHERE THEY PURCHASE SLEEVES. CONTACT THEY'RE REP. THEY ARE NO HELP AT ALL AND WILL NOT GIVE ANY INFORMATION, PROMISE TO RETURN CALL, THAT DOES NOT HAPPEN. THESE ARE HANGING SLEEVES BUILT TO THEY'RE SPEC'S. GENERIC SLEEVES WILL NOT FIT. DO NOT WASTE YOUR MONEY I DID AND THREW AWAY 100 SLEEVES. AMAZON DID CREDIT ME BACK 10% ON PURCHASE. THIS SAFE IS A WASTE OF MONEY!
SENTRY IS INTERESTED IN SALE ONLY! NOT CUSTOMER ORIENTATED.
