These inks are professional quality and are the products I use in making my own prints. They are also some of the most eco-friendly available.
They are oil based but still water washable which makes clean up super easy. They're made using linseed oil.

Please select which colour(s) you would like. 

Available colours are:

Black, Process Red (magenta), Process Yellow, Process Blue (cyan) and Pthalo green (dark turquiose)
