I bought a "German-made single-blade razor" because I admired it, but it didn't suit my skin, so I haven't used it and it's just been for display. There are absolutely no problems with its use, and there are no scratches, dents, or damage to the screw parts. I have disposed of the outer box, so it's just the razor itself. Here's the product description: Exhilaratingly close shave Double-edged razors give a smooth finish like you get at a barber shop. You can get an exhilaratingly close shave that you can't experience with electric shavers or cartridge razors. Even if you've never used a double-edged razor before, you'll be able to shave well after a few shaves, even if you're not used to it at first. "Comfortable usability and beautiful form" Shaving products from "Mühle," which is highly regarded worldwide for its functionality and design. Pursuing the feel on the skin and the shaving experience, this double-edged razor is carefully finished with gleaming chrome plating, giving it a unique sense of luxury. Reasonable replacement blades Replacement blades for double-edged razors cost only a few dozen yen per blade. Cartridge razor replacement blades cost about 400 to 500 yen each, so double-edged razors are very economical. You can use blades from any manufacturer with double-edged razors.
