Endless Alchemy-Candy Seas - the ink color is very good, it has a very unique sapphire blue tone to it. The bottle design too is very creative, whilst staying stable on the desk. I had no problems filling my fountain pen with this ink. It flows well and doesn't stain a lot (got off the ink I dropped on my hand very easily, it didn't stain my dip pen nib either). The ink is not permanent, so one has to be careful while writing with it to not spill any water or other liquid on top of the papers. The drying time with my sailor pen was around 15-20 seconds (while it took much longer with my dip nib, which I expected since it puts down more ink compared to my FP). I dont think that the ink is too dark that it crosses over into the blue-black territory. There is a noticeable purple sheening, the sheer is bright on the letters I have written by the dip pen, while more subtle with the fountain pen (it is a reddish-purple color, I am not sure if it is captured well in the image). I have attached an image for reference. To conclude, a good, affordable ink brought by Endless at INR 949 or USD 11.50.
Initially when I received the ink, it was spilled and leaking. I immediately wrote back to the company and they sent me a replacement bottle. This is the only reason I have deducted 1 star else this is a 5 star rated ink. The colour is awesome, nice sheen on tomoe river paper, wet flow and a cool bottle. I really liked the colour a lot and like other products of this company, they have come out with a wonderful product.
