found in 1917, GEKKOSO artist's supply, has been offering supplies for painters that are only handmade by japanese artisans. back in 1940, they developed this colour named the cobalt blue shown in the world standards colors list. then came the cobalt violet pink, another colour invention that the french paper le monde called, "a miracle that occurred in a country other than france." another snazzy thing about this establishments in the old classy district of ginza is the sketch book -- it won't swell with the painted watercolours & the paper won't get tanned shortly. in case you wonder what does the name "gekkoso" means, the definition is "the house of moonlight"
