A small white plastic ring to hold the spring and is worn out with me after little use. Since it can not last for a very consumable looks that definitely I Alfi written, there I may leave for 8 provide a new cover. Trusting in a quality I have unfortunately no longer the bill. It's really very annoying that with a se-quality product such vulnerability has been installed!
