Standard Parker style refills, made in Switzerland of Swiss components and Swiss made ink.
Gel ink is generally water based and ours is no exception. It has a higher viscosity and contains a greater concentration of pigment than our standard ink. Our Parker style gel refills are extremely popular as many prefer the end result. They are more opaque and are also capable of writing on surfaces where an oil-based ink won’t work, for instance, on glossy paper or plastics.
