While i couldn't find anything whatsoever any this brand online, I am pleasantly surprised at how competitive these are with big name brands like copic or spectrum noir. The pigments are great, they blend and layer well, and work well with colourless blenders of various other brands (does not come with one). The skin tones in particular are excellent in colour range from dark to light with a variety of undertones that you can make use of by layering – 6 markers equal more than six skin tones in this pack! You're looking at around 3 dollars per marker compared to 8–13 dollars per marker for expensive artists brands, so the value is absolutely there. 10/10 recommended.
