This is an automatic lens cap specifically for the M.ZUIKO DIGITAL ED 14-42mm F3.5-5.6 EZ lens. It automatically opens and closes with the lens's retraction/extension, eliminating the need for manual removal and the worry of losing it. - Model: LC-37C - Color: Silver - The barrier functions well. - It has been used infrequently and is in good condition. The outer box will be flattened for shipping. Thank you.
