The photo says it all storing 75 33-rpm records. Our new triple-walled Storage Box is designed exclusively for LPs! The 13” depth means you can stack these boxes when full, unlike similar boxes that are only 10” deep. These boxes are virtually indestructible, attractive, and best of all, affordable! New lid design makes these even better. Ships flat with assembly instructions provided. You will not find a better or stronger cardboard LP box anywhere! Exterior measurements including lid 13.5 x 13.5 x 13.5 inches.
