This is a beautiful flask with almost glassy feel to touch, its impression is pure and transparent with a colour of Lapis Lazuli.
Its waving pattern is drawn with “Icchin” technique to draw three-dimentinal lines, then apply glazing. This way, it create a clear pattern on the surface.
Its colour reminiscences deep ocean and is very refreshing to look at, and it is perfect for enjoying cold premium sake.
There is matching sake cup available here.
