It was great that the image quality wasn't as bad as I expected. Next time I buy it again, I think I can refer to this and make the color brighter. When I made the background transparent, there was a picture border that was invisible to the eye, so next time I'll have to use it in a square state without the background transparency... The case opens right away even when I shake it slightly downward, so it would be better if this point was improved.
