Cat Pure Crystal Full Circle Filter 7 pieces

Selling because I stopped using Pure Crystal.

I discarded the box and kept it in storage.
There is a GEX marking on the back. (See 2nd image)
The brown filter at the bottom right (only 1) has a plastic brown part. (I think this is from before they were all soft.)

I am also including the original points paper that came with it, as I haven't used it.

Price reduction ?
Immediate purchase ?
