They're definitely great value Paul. Interestingly I bought 100 GSBs at Christmas and they were cheaper than when I bought them from the same seller earlier in 2019. Their price seems really unsteady. Great blades though.I concur, Chris
Two shaves in with one of these blades.
They are the real deal, without doubt.
At £12.30 with free postage for 100 blades is a decent price too.
Incidentally, Silver Blues seem to have gone up in price since I last bought some.
Given there is very little difference in performance between the two blades, I'm happy with the Platinum's.
