This is a frame CPL filter for a KANI 150mm filter holder. I am selling it because I rarely used it after purchasing it. It has been carefully stored in a dehumidified storage box, so the condition is like new. It is currently discontinued on the KANI website and is no longer available. The included accessories are all shown in the photos, and there should be no missing items. As shown in photo 5, there is a partial tear in the band of the packaging. Please feel free to ask any questions you may have. I am open to discussing price reductions, so please consider purchasing. 【Product Description】 Brand: KANI Coating Description: Low-reflection coating Photo Filter Effect Type: Polarizing 150mm width holder with frame CPL While 100mm holders use a design where the CPL is attached to the holder, 150mm wide holders are designed to minimize vignetting by not allowing space between the lens and the holder. Therefore, it is designed to be used by attaching it to the filter frame, rather than attaching the CPL to the holder. Ease of setup is also a feature. Low-reflection coating, waterproof and dustproof
