Nearly everyone know of Sailor, the Japanese pen and and ink company. Perhaps almost as many people have heard of Bungubox, often just called Bungbox here in the US, the Japanese stationary, pen, and ink shop in Hamamatsu, Japan. Here is a nice google map for you to locate it when you travel to this area of Japan to see the Hamamatsu Castle.
The have an extensive line of inks made for them by Sailor, and during the craze for Sailor Japanese store-exclusive inks Bungbox became very popular and with that the price went up, and up. Even in Japan they are much more expensive than other store-exclusive inks. Vanness actually have the Bungubox inks available, but you will but up $43 for a 50 ml bottle. For some, this price is worth it, for the inks are exceptional. I have a number of their inks from before the craze, and a few I got as prices were rising, but so far I have resisted the current nose-bleed prices. Though Sweet Potato Purple was very tempting.
But Fresh Oranges is somewhat legendary among the chasers and collectors as a great orange. Perhaps along the lines of Sailor's Apricot. I've never tried the latter so I cannot say. And I must admit that orange inks are nice, but I often find them to be a little light in value, and therefore, harder for me to read. But they can be very inks especially for cards, notes to friends and family, and your journal writing. Orange is a happy color and one that will never bring you down.
I received a nice sample of this ink awhile back when I first got involved with orange inks. Thank you inky friend!
Many orange inks seem to have flow issues compared with other inks. I think part of that is their lightness, and if you want any other quality you can't have a gusher of an inks. BB Fresh Oranges is very good in that regard. It has great shading. It's a very nice orange ink, not flat. But it is very close to Sailor's Kin-mokusei. They are different, but only you can decide whether you want to spend $18 or $43.
Others will probably be able to explain more on how this ink is, and how it differs from others, and why they love it.
