Boysenberry is formerly from the Swift Formula collection where the inks were designed to be wetter than average and performs well in a wide variety of fountain pens. The company had since changed their ink collections and this ink is now found under the Keystone Formula collection.
This ink is a medium purple with shading and no sheen. The ink has a very wet flow. Due to the wetness of the ink, it will perform well on some papers and worse on others. I think the ink will be more suitable in drier nibs.
On Tsubame Fools paper,
- Shading: Yes
- Sheen: Nil
- Feathering: Tiny
- Bleedthrough: Nil
This is written with a TWSBI ECO-T medium nib.
