Yes it is made in china. But what isn't these days. The brand is run from the Netherlands if i understand correctly. The holder itself is very unique and seems very versatile, especially with the polarizers. Their filters are made from
Schott glass so I imagine the quality should be quite good
Originally posted by biz-engineer Kase is one more chinese brand of square filter systems. I don't know the quality. What I know from experience: it is hard to find good filter glass together with good filter holders and reasonably priced. All filter systems are largely overpriced and the build quality is often very fragile (=cheap).
