Review on Merkur Razor Double Edge Razor Blades by Kari Harden

thought I would buy a box of 100 instead of 10 - it's my fault but I would never knowingly pay that much for 10 razors. Much more expensive than some competitors like the Astra Superior which is around $25 for 300 razors and has served me very well for many years. If needed, each Astra lasts a full week (I used it probably 10-12 times before throwing it away). These mercury actually feel a bit dull on the first shave and I'm not sure they will last more than two or three uses.
