Looking for new/sealed blank high bias type II cassette tapes

Ok, it was worth a shot. 

That's the one, @atmasphere , I couldn't remember their name. They use a cobalt formula for Type II tape.

To my knowledge the only cassette tape made in the US made by the premium US manufacturer of tape.

Good luck to you.

I have found them on Craigslist before for super cheap, $1-$2 each, brand new. So I’m just asking in case someone wanted to get rid of them. eBay prices don’t mean anything to me, they don’t control what I’m going to pay.

Yes, good luck finding them for 2 bucks! I've seen some on ebay in the 25-40  range! I bought many sealed cassettes of various brands, tdk, maxell, basf, realistic, etc....however, I'm hanging on to them. I don't have anywhere near 100 of them, but what I do have will last the rest of My life I'm sure.

Take a look @ tapes.com.

Not familiar with them myself, but they are located in the USA.

Hate to tell you, but sealed tapes go for around $10.00 a piece. I buy used ones for around $2-3.00 when I need them now. I have a Nak and I completely erase them before I re-record over them and that works out fine, no bleed through that I can tell. And good brands like Maxell and TDK rarely have drop outs. So you can try what I do. 

I say that because I remember selling boxes of 10 of either Maxell/TDK for $18-20.00 back in the 80's, so $2.00 today for sealed is not going to happen unless someone is very generous. Indeed, with inflation over the last 40 years, and no new production to speak of, $10 a tape sealed is actually a "fair" price in today's market. Best of luck regardless.
