## Description

Six (6) individual - factory wrapped - TDK Superior Normal Bias D90 Audio Cassettes.

Review: Take care of them and they'll last forever! - These tapes are EXCELLENT QUALITY tapes! I use them & got some for my brother. We swear by them that they last forever as long as you don't break the tape. The sound quality is as good as new even after 20 years & more of playing and even if you do break a tape you can splice it back together and it will still sound good (as long as you do a good splice job & cut off any damaged or really wrinkled parts). Love these tapes!!!
Review: It's a late D, and it's Really Good! - These NOS TDK D's are really good. Don't be fooled because it's a D (Type 1, normal tape). This is a late D, and the quality tape formulation inside it, is nearly as good as the Type II's, or Type IV's of previous generations. With a good 3-head deck and calibration, you can get some amazingly good recordings with these.
