This ink is a part of the re-release of Sailor's 2010 limited edition seasonal inks. Now it has been made part of Sailor's standardn ink lineup after they had discontinued a number of well loved inks. It is no wonder I had such a hard time sorting out if the inks were new or old. Oku Yama translate from Japanese to English as deep mountains. This is one ink that should be used on good paper. The ink shades very well from a brighter pink purple to a deep wine red on good quality paper. However on a medicore paper, it dulls into a red-brown and shading is all but gone. There isn't any bleed through on bad paper though. This shade of red reminds me of Pilot Iroshizuku Yama Budo. Oku Yama is also known to have a green sheen from a few examples I've seen online. This is a well behaved ink that has many sought after properties by many ink lovers.
