Review (5/5): They sure are...
Razor blades. They dont seem to keep as long as some brands but i appreciate not having to just get 5 at a time at the hardware store. I dont know how the plastic package will hold up. Also i guess if i had to pick i would prefer less razor blades regarding the disposal of them. I cannot guess what happens to them at the dump but it screams tetnis to me. Im sure 100 blades will last a while though. Need for utility knife. ;)
