This is an adjustable double-edge razor holder that allows you to adjust the shaving feel. By turning the dial at the end of the handle to change the blade angle, you can adjust the shaving intensity (1 = mild to 9 = hard). The body is made of metal, which provides weight and allows for stable shaving, and features a 2-piece design where the head base and handle are integrated. The dial also functions as a cap removal mechanism; if you continue to turn it past 9, the screw will loosen and the cap will come off. There are irregularities that fit into the head and cap, and the screw will not tighten unless they are fitted in the correct direction. Please be careful when attaching replacement blades (see image 6). The box says it contains 5 replacement blades, but they are not included. Please prepare replacement blades separately. -- Product Specifications -- 【Brand/Product Name/Country of Manufacture】 Ming shi Shaver5000S / Made in China 【Product Contents】 Double-edge razor holder 【Dimensions】 Holder: 4.1 x 2.6 x 10.3cm / Box: 5.5 x 2.8cm x 15.3cm 【Weight】 Holder: 84g / Total weight: 99g 【Color】 Silver ※Depending on the individual product, there may be rust or what appears to be peeling of the plating on the core rod of the cap (see image 7).
