There’s some ND filters and also other unique ones like blooms and soft hazes and ones that make light streaks.
I bought it directly from a Chinese supplier so I’m selling the case and all the filters. They are magnetic and stack on top of each other but they suggested to stack 3 max at a time to avoid them falling off.
Worth noting, there’s 6 filters in total.
3 of them stack on top of each other perfectly. And the other 3 stack slightly bent just because of the magnet orientation.
