The comb-shaped design makes it easy to apply, and it really does create separate lashes! The liquid has a slight viscosity, which I found similar to Kingdom's curling mascara. I think Kingdom's mascara doesn't contain fibers, so I think Won Jong Yo's gives more natural length. One coat gives a natural finish, and two coats can be used even with heavy makeup. It doesn't clump easily, so it's easy to use. It contains a small amount of fibers, so it gives natural length. It also comes off with warm water, so it can be removed with regular cleansing oil, which is great. I bought the sheer brown, but maybe my natural lashes are too dark (lol), so I don't really notice the brown color. Honestly, it's no different from other black mascaras.
