iPhone 13 Tough Case, Glossy
Wow! For $20 I wasn’t expecting something phenomenal. I was expecting maybe a fuzzy picture but good enough. It’s clear, crisp and looks great! Case is protective.

Everything about this case is fine. I added my own text came out well. I ordered the color black but the sides of my phone case are a faded dark green, not black. And there’s some sort of white shadow on the corners of the vase as well. Not too crazy about that pretty disappointed. Text is good. Clear
