These blades are made by Gillette (Procter & Gamble) in Russia. We find these blades to be smoother and sharper than the more well known Astra Superior Platinum Blades. A review of these blades can be seen at therefinedshave.com here. There is also a review on the youtube channel of Ken’s Shaving here.
Sold in two packs of 5, 10 blades in total.
