All is like it should be - quickly and quality is 100%!
I've finally received the case. It took about 3 months. The seller they said it was because of COVID-19's shipping problem. Anyway, the case for oneplus 5t is just great. But one point I got very sad is that I had ordered the gray and white one, but the one I received is black and blue one because of the shipping problem.. However, this one is also okay, thank you.
