Silicone case and leather case have their own merits and weaknesses. In order to achieve comprehensive protection, another mobile phone protective case has been developed.
Crystal shell This is the crystal shell favored by women. It is made of plexiglass, with a thick and firm appearance and a crystal clear shell. Not only can it effectively protect the phone, but it also doesn't affect the appearance. It can be said to be as long as a silicone case and a leather case. However, the purchase of crystal shells is also more challenging. Although the cost of crystal shells is not high and the craftsmanship is relatively simple, some businesses can save on workmanship and materials in order to earn higher profits.
First of all, the appearance of the crystal shell depends largely on the abrasive tool. The abrasive tool is good, and the quality of the crystal shell made is too hard. The size of the crystal shell made by irregular abrasive tools will be deviated, and some cannot even fill the mobile phone;
Secondly, the thickness of the crystal case is stricter. If it is too thin or the hardness is not good, it will break easily. If it is too thick, it will affect the operation. In addition, since it is called a crystal, the outer shell of the crystal shell must be transparent, but some crystal shells are gray or even yellow, which is another problem of cutting corners. Of course, the crystal case also has drawbacks. Because it has a certain degree of hardness with the mobile phone, the two will inevitably produce friction, especially the corners of the mobile phone. Usually, the four parts of the mobile phone are the most severely worn. Be cautious when shopping, don’t be afraid to compare goods.
