PDMagnetics 500 Crolyn - 1983 - EU(CH)
Made in Switzerland
The surprising thing about this cassette is that it had clear shells. At the time, 1983, almost all top brand cassettes were all using high quality and heavy plastic black shells. Some were using clear shells for some of their type I tapes, or a combination of clear and black plastic to create some of the most beautiful tapes ever made by the industry. Clear shells for a type II cassette was definitely not common.
Note 1: 90 minutes: Lightly scuffed wrapper, but no cuts and no rips. It's got a nice quality and nice looking label. See the 3rd. picture! Only 1 available.
