Canon EF-S 18-55mm F3.5-5.6 IS STM This is a lens, an accessory for a camera. There is no mold or fogging inside the lens. I believe there may be some dust and debris. I have only used it for test shots since opening it. The exterior is very clean. Includes front and rear lens caps. I believe the overall condition is good, but please understand that this is a used item. If you have any questions, please feel free to ask.
