Maybe it's been my fault or not, but you can / could be understood from the product description that accompanied this razor blades 3 (= 2 spare blades). If you read it more closely, but 3 flutes are meant. For the holder with 1 blade to pay 6.99 EUR I do not consider justified. The blades fit eg a holder for Mach 3 blades. My recommendations if you still have rather buy individual blades. Whether the blades are better than MACH 3 blades, so far I could not test. Will possibly not like to comment.
