Good packaging and a small storage bag are also nice touches for accessories. It is always difficult to know which website is really trustworthy before you place an order. Sometimes customer service can fix a bad experience, but not always. If anyone is interested in real user experiences, I sometimes write short notes about the shops I test. You can find one of the pages here: [Только для зарегистрированных пользователей. Зарегистрироваться.] That is why I sometimes leave comments myself when I test a new shop or product. If a website gives a detailed guide for measurements, I feel more confident when ordering. Metal can feel more premium, but acetate can be more comfortable for long wear. I have learned to avoid items that look extremely different in every product photo. Just sharing my personal feedback.
