Buying One (1) New Old Stock (NOS) Black VHS Clamshell Case.   Was in storage for many years as it was still in the original shipping box.   However, please note there are noticable nics, smuges, dirt, etc on these after being stored so long.  These are not meant to be collector/museum quality. PLEASE SEE PICTURES. 

The plastic cover is open on both ends.  The insert space is about 4 3/4" wide x 7 3/4" talk on each side, the spine is about 1 1/4" wide.  So an insert of approximately 10 3/4" x 7 3/4" should fit.  These are approximate measurements and could be slightly off.
