but frankly I kick myself in the but to not have bough any GSB last year
Still available on Amazon for $15/100. Same price they have been for the past few years.
I have a stock of them. If you really like these blades (I do), I would stock-up while you can still buy them as PPI originals.
I think US made Personna Lab Blues, are similar. I use them too.
I think the Treet Kings are as good as or better than these or the Voshkod's. At $8 per-hundred on Amazon, I think they are the best DE blade value out there. I picked up a nice supply.
