For some reason, the seller provides incorrect information: if you have a 72mm lens, the lens cap you need is the 62mm one.
In my case, the original Sigma 18-35 lens cap still works perfectly on a K&F filter, but I was looking to replace the lens cap with a silicone one, which I find more comfortable and has a better grip.
Despite its thickness, which may raise some questions, it can still be attached to the lens with the lens hood (see photo).

I got it to go with my new K&F variable ND with the putter on the side. Hate that they don’t come with covers so ordered this, took an X-Acto knife and just cut a notch out for the putter and it fits perfectly over the 82 nd filter.

This is a little loose on the 82mm Polarpro variable ND filter. I understand that it’s not made for the Polar Pro brand, BUT it fits well enough! I had contacted Polar pro customer service about getting a replacement cover for my ND but never got a response. They do have their defender series but I was looking for something that was low profile. If you’re in need of a cover for your polar pro, this works pretty well.

First annoyed I had to replace the Fujifilm lens cap--turns out this one is superior. The original Fujifilm lens cap--at least mine--was fiddly to pinch onto the camera and came off at the lightest touch. This replacement is more secure on the lens and feels more durable. As much as I love Fujifilm's gear, Breakthrough Photography totally one-upped them here. As a bonus the little flame logo gives it a custom look and they threw in a polish cloth.

It's a great product! I've lost a cap from my old film camera and thought that it would be impossible to replace it, but luckily I found this one and it fitted perfectly. Reasonable price, good quality. My gratitude to the producers :)

The cap is nicely built - a combination of plastic and silicone material. It's pretty much a must-have, if you want to protect your expensive filter, while in use. The only criticism would be, that it doesn't fit the new CPL & ND2-32 Nano-X filters, which are wider than the other variable ND filters and, of course, have the orange handles. If such a version of this cap is created for the CPL & ND2-32 Nano-X filters, that would be very nice and I'll be getting one ASAP.

The 77mm lens cap is not too tight that it's a pain to get on and off but also I don't think it'll fall off in the bag. Kinda perfect sweet spot for the Tiffen 72mm Variable ND.

I put polarpro defenders on all my lenses because they cover most filters, offer protection, and they’re a lot harder to lose than an OEM lens cap. This new offering from K&F is awesome and will work with my filters. It’ll fit better in the pocket while shooting also. I’m headed over to buy a second for another lens.

I think it would have been very inconvenient to use the ND filter and not be able to protect the lens when not in use, I am very glad that I also bought this lens cap, it is very well made with excellent quality
