It is light and looks good.

Since it is a product of the super fine sunstar, there is no worry about quality at all.
I bought it cheaply and picked it up with a monotaro that reaches my home and it was the correct answer.

It is favorite because it is cooler than genuine and cool.

In terms of product, there is no distortion, so accuracy is good so there is no problem. It is about going to wear degree by use afterwards.
