Action camera neutral density filters. CPL ND8 ND16 ND32 Set of 4 filters. I purchased these for the Osmo Action 4, but I'm selling them because I don't need them. I only used the ND8 filter once, and the rest are unused. Please check the condition in the photos and only purchase if you are satisfied. I may change the shipping method between Rakuraku Mercari and Yu-Yu Mercari. 【Important Notes】 * Cancellations after purchase are not accepted. Also, returns are not accepted to prevent product substitution. * I am not responsible for any shipping-related issues after the item has been shipped. I am a non-smoker and do not have any pets.
