Sweetheart used to be part of the Crisp Formula collection where the inks were designed to work well on a variety of papers. Birmingham has since recategorized their inks and now this can be found under the Keystone Formula collection.
This ink is a bright pink, almost fluorescent, with a tinge of orange that comes out in the wetter areas. The ink has an average flow.
On Clairefontine paper,
- Shading: Yes
- Sheen: Nil
- Feathering: Nil
- Bleedthrough: Nil
This is written with a TWSBI ECO-T medium nib.
Below are a couple of photos of how it looks when it was written on both sides of the paper.
