Pilot bottled ink 'iroshizuku kon-peki(Deep Cerulean Blue)'

Pilot bottled ink iroshizuku
(Deep Cerulean Blue)

"kon-peki" is meaning bright blue in Japanese.  Especially it is used when express of very sunny sky.  This color seems almost does not contain reddish elements.  I recommend this color as a very purely blue.
