Lot Of (21) Sony PR-150 Reel To Reel 7" Recording Tapes w/ Boxes - EX Condition

One of these tapes appears to be unopened (see pic #3), the rest have been opened and may have been recorded on.  All of them still have the original plastic protecting the tapes (see pics), and are very clean looking tapes.

Some of the boxes have writing on the back, some do not.

Please ask any questions you have before buying

THANKS!
