The coating of frosted glass is basically in a sealed state, so we can't judge the nature of it. For example, the hardness and abrasion resistance of the coating require glass frosted materials in the formula. Looking for important judgment factors from other aspects, we can mainly judge from the following aspects:
Important factor 1: Select well-known brand products. Look at word of mouth. Query related product quality and safety. Generally well-known brand products will be stricter on themselves in these aspects.
Important factor two: choose a large shopping mall or specialty store. Generally, products in hypermarkets must pass the qualification inspection, and the quality guarantee of glass frosted materials must pass. When buying, be careful not to fully obey the words of the seller, you must have your own opinions; at the same time, you must strictly check the product batch number, production date, warranty period, security mark, customer service phone, manufacturer address, etc. on the outer packaging.
The most important point is that you must ask for invoices and inspection certificates after purchase. This way you don't have to worry about the product being purchased without protection.
Important factor three: Choose a moderate price. Ask for more prices. Choose a moderate price after making comparisons.
