Very sharp and long lasting [SEP] I purchased a 100 pack (20X5) 2 years ago from Amazon. I had tried them as well as other inexpensive Russian(Gillette) Rapira or Gillette Platinum. These blades are Teflon coated however; some lots are marked as Teflon coated, and others are not! Not sure why but I have been assured they are all Teflon coated and the branded Dupont Teflon name may not be printed due to cost for using the word Teflon. These Voskod as well as their sister blade Rapira are excellent blades. Note the reverse side of the box and you will see (rapira.ru) at the bottom. My favorites blade of more than 20 that I use.
