Shavers and replacement blades

A literal revolution in the field of "disposable" shavers is being brought to the market by Preserve. The company produces shavers with replaceable blades, so the main part stays for a long time, you can only replace the worn out shaving head. But that's not all, Preserve makes its products from recycled plastics, specifically yoghurt cups. So you actually save waste twice. Another sustainable solution is a metal razor with replaceable blades, it takes a bit of practice but it does a great job!
