There are many designs for your phone holders. And many of them are presented on this site. But I think the most convenient design. It is light, small and convenient. It is always comfortable to carry and expanded at any time.
The original model I ordered a couple of years ago in China. I wanted to repeat this practical form, and when I reached my goal, I decided to add a little beauty and uniqueness. So I got two versions, the first simple and practical, the other more beautiful, but no less functional.
