Among all kinds of protective sleeves, leather protective sleeves for mobile phones are also very popular. Compared with a single-style silicone case, business people who work hard in the workplace prefer to use a decent leather case. Unlike young people who admire leisure, holding a mobile phone with a single color is not elegant for them. Similar to silicone cases, there are two types of mobile phone holsters. One is a waistband holster that has been popular for many years, and the applicable type is more common; the other is a portable holster that can be put in a pocket. Different, but the manufacturing process is still similar. The advantages of portable holsters are chic, elegant, non-wearing mobile phones, and good heat dissipation, but they are not waterproof like silicone cases. At the same time, if the holster is too large, it is difficult to fit into the trouser pocket, which is somewhat inconvenient to carry. The quality of the leather case is also uneven. Although leather cases can be seen everywhere on street stalls, you get what you pay for. Natural leather materials of more than ten yuan will not be made of genuine leather. Most of them are artificial leather or fake leather. The phenomenon of cracking and glue will appear soon after use. The leather is durable and has a long service life. Of course, the price is not cheap, and the price generally ranges from tens to hundreds of yuan.
