One of the problems that wet shavers have is what to do with the used blades, how to dispose of them in an environmental friendly way. Since DE blades are 100% metal, they can be fully recycled. So, how can we safely keep them until we send them to recycling? Well, we can buy a blade bank or we can do something even better: make our own Used Blade Bank from a Coca Cola can like the one I made. 😀 You can find the nice label here: How To Grow A Moustache.
