This lot includes two sealed Ampex 456 7" reels of 1/4" x 1200 reel to reel tape. These vintage blank media items were manufactured in the United States and are ideal for use with vintage audio equipment.  These have been properly stored, have never been opened, and are still in the totally intact shrink wrap.  Having said that, these tapes are over 30 years old and can't be fully guaranteed.  But, I am sure you understand that.  Chances are, they will work fine.  Just make sure to keep those heads clean with your Q-Tips and alcohol.
