I don't smoke, and I don't have any pets. The item is stored in a room with temperature control via air conditioning. This is a KANI HT PRO+ MC UV-IR-CUT 105mm diameter lens filter. I only attached it to a Sony FE 400-800mm F6.3-8 G OSS lens and took one test shot after purchase. As you can see in the second image, this filter produces very clear results. There are no scratches, and I have not touched or wiped the lens part. I will lightly tape the corners to prevent the contents from moving during shipping, and I will ship it from the Yamato Transport office in Kanagawa.
