NiSi 72mm Metal Stack Caps

The magnetic threading on these caps makes stacking filters feel much more secure, and the metal build is a nice upgrade over the usual plastic. Screwing them on and off is quick, and they keep my filters dust-free in the bag.

I’ve been looking for a way to keep my stacked filters from gathering dust between shoots, and these caps thread on smoothly with a satisfying click. The metal build feels solid enough that I trust it in my bag without a separate case, and they haven’t loosened once during a week of hiking.

These metal caps screw on nicely and keep my filter stack from coming apart in my bag. The threading is smooth and the build feels solid for the price.
