These frames are a great idea in handling the K&F filters. The filters fit nice and snug and are easy to put together. However, they are hard to take apart if needed. I like the idea of using the frames to help eliminate finger prints and smudges. Great product.

I was pleasantly surprised, as I had no idea there were two! Perfect for matching the 100x150 filters (2mm thick) with the K&F Concept Nano X-Pro system.

Perfect for 100x100 and 100x150 filters. I have used them for K&F Concept Nd filters and other brands like Neewer and Zomei; in both cases, they fit perfectly.
