This is the patented razor cleaner that removes shaving grime that can dull blades, extending their life up to six times. Simply coat the cleaner with shaving cream and push the razor across its surface several times. Friction from contacting the cleaner's flexible silicone surface removes organic buildup from the blade's edge, similar to a traditional leather barber's strop. As a result, new blades remain sharp for dozens of shaves, so one needn't buy costly replacement blades as often. The cleaner works with all manual razors, from single-blade disposables to multiple-blade cartridges, even DE safety blades. About the size of a smartphone, it comes with a space-saving stand that stores the cleaner, a razor, and extra blades. 5 1/4" L x 2 1/2" W x 1/2" D. (4 oz.)
