Looks like a copy of the wide-mouth double-knocks made by OHTO, Niji, Platinum, Staedtler, Tombow, and Stabilo. A more recent release, I think. From what I can see, the quality may not be on the same level as the vintage examples from other brands. Anyone here have one of these?

My own w-knock clone obsession has abated somewhat 
After 4-5 variants of any type, it becomes difficult to raise my interest. This particular format has been covered by Sun-Star and Tomato amongst many others. A properly thought-out clear tinted version might be worth considering!
In the same vein, the recent Sakura Writoll series was yet another regurgitation of the rubber-grip w-knock format. I was only keen on the 0.3 models and some of the more interesting colors for 0.5.
