This listing is for the following items: 【K&F CONCEPT CPL Camera Lens Filter Ultra-Slim Optical Multi-Coating Circular Polarizer 39mm】 and 【Camera Lens Hood Metal Ventilation 39mm】. Both items are practically new, having only been tried on. I purchased these items at the same time as a lens, but the lens's focal length wasn't what I expected, so I sold it immediately. Therefore, I am selling these items without having used them. Please note that I believe the filter and hood cannot be attached simultaneously. I kindly request that you refrain from complaints or returns after a transaction is completed.
