Welcome to the new Birmingham Pen Co. ink comparison tool, Inkvestigator.
Nick created this app with one hand while chasing his ten month old son around the house so it's still very much in the alpha stage. Only the Crisp Inks are live as yet but we'll have more available soon.
Simply select any ink color from the dropdown, then freely drag and rotate the swatch. Any number of swatches can be added simultaneously.
