- The case is designed to pull the moisture off the blade and sanitize it at the same time. This will save you money. The handle of the razor goes in at a slight angle so that the blades does not touch anything. The case is made of hard plastic so the hinges will not break. There is not a place for extra blades, because your razor will last a long time. On a monthly basis, you should wipe the interior with disinfectant wipes to keep the case clean inside . After 6 months of use, you can put it in a microwave without the razor at 30% power for 30 seconds to remove any built-up moisture.
