I am thinking about buying 100 of 7 o' clock yellows. I have so many blades now but these are are so good.
I bought 400 Voshkods, 200 Rapira Platinum Lux, 200 Lab Blues, and 100 Astra SPs.
I am set for a while, but I make no promises not to buy more blades.
I just wish that Astra was not owned by Gillette.
