he mobile phone protective case is a product made of metal, plastic,
silicone, etc. The mobile phone protective case basically has three
functions: protection, decoration, and function. Mobile phone protective
cases are no longer a purely practical commodity. With the popularity
of mobile phones among young people, almost every young person who
pursues fashion wants to have a unique mobile phone. Grooming their
phones has gradually become a way for them to show their individuality.
In response to this trend, phone case makers have introduced a number of
products with better workmanship and more unique color patterns. This
makes the types of mobile phone cases more diverse. When purchasing a
color cover, first check whether the background color of the color cover
is similar to the color of the surface. Simply put, the plastic
material used for the white shell should preferably be white, and the
plastic material used for the black shell should be black. If the base
color is similar to the color of the surface, even if the surface
coating of the color case is scraped off in the future, it will not
become unsightly. The specific inspection method is to first turn over
the color shell to see if its inner surface color is the same as the
outer surface; secondly, check whether the color of the color shell is
uniform; check again whether the printed pattern on the color shell is
within the specified range, if the edges of the pattern are all If it
extends to the inner surface of the color shell, it means that the
craftsmanship of this color shell is not good enough, so it is best not
to consider it; finally, be sure to remember to check the shell body for
scratches and other problems.
