I just filled my tester pen, Yibu 106, with this Sherwood green, and the entire nib of the pen is covered in it. Also, the ink creeps like the tides, when I write it comes out, when I'm done writing and I leave the pen alone for a while, the ink recedes so there is only a very small amount of ink on the nib, that is until I begin to write again.

Any idea to make it less creepy or less fast drying (it dries while still in the nib)?
