Polymaker filament has always worked well for me. This one is from their PolyTerra line, so it has a percentage of minerals in it that it give it a very flat/matte color (basically no sheen). This is definitely VERY matte. I bought this looking for a unique color and it delivered. Its combination of white and black makes for a very "shadowy" appearance as you can see in one of the prints I made with this filament. I would say it is kind of a novelty color and to be honest I have only used it for a handful of prints. But I think it is good for times when you want something "between" white and black that isn't just grey. So while it will probably take me a year or two to burn through the whole kilo, I do like it a lot.
