Review on Ultimate Quality Double Edge Razor Blade Sampler - Astra, Derby, Shark, Voskhod, Bolzano, Treet, and More! by Amy Blackmon

Unequal blade set. The worst are Treet Ten Blades (Pakistan), which deserve 0 stars: rusty, dull, irritating to the skin, unusable from the start. Blades Ten Shark (Egypt) 2 stars for sharpness and durability, satisfactory for two chips. Blades Ten Derby (Turkey) 3 stars for sharpness and 2 stars for durability Five blades Bozen (Germany) 4 stars for sharpness, 5 stars for durability Five blades Voskhod (Russia) 4/4 stars And the best in this set 10 blades Astra ( Russia) 5/5 stars. Conclusion: minus 30 useless or almost useable blades, I only paid full price for 20 blades. The rest is simple arithmetic.
