Kingdom note is a stationary shop based in Tokyo, Japan. Like Bung Box they have become extremely popular in recent years, in large part due to the famous vase- shaped bottles they used. I believe there a couple of other Japanese stores using these bottles, but they are all now migrating to the standard Sailor ones. Kingdom Note line of ink was retailing for a long time on ebay for around $50 or less with free shipping. Now they are going for crazy prices.
I used to have the Mushroom line of inks but found the colours were very unsaturated and quite dry as well, which I didn’t really like. I ended up selling all four of them. I regret it slightly now, but at the end of the day I wan’t to be able to use the ink, not look at the bottle!
I held on to two of the Kingdom Note inks- the Stag Beetle Grey below which is nice and saturated and isn’t dry at all, as well as the bright orange/ red Nippon Nipponia, which is actually quite similar to the Mushroom series’ Ammanita Muscaria.
