Socimag DCII - High Bias - Type 2 - New Blank Cassette Tape
These contain AGFA Type 2 tape.
Although these aren't pure chrome, you will still need a deck with manual calibration facilities to make the best of them. When you have, you'll find these are fantastic sounding cassettes that offer real value for money.
Here's a review:
Although the wrapper says 90 Minutes, on testing, we've found these are more like 88 Minutes.
*PLEASE NOTE* - Although brand new and sealed, there will be some damage to the outer wrapper. These are for using, not collecting :-)
