This is the perfect kit to get you started with fountain pen ink mixing! Contains approximately 1/2 oz each of Noodler's Navajo Turquoise (cyan), Shah's Rose (magenta), Yellow and Black ink in eyedropper bottles. These 4 colors can be used to create a rainbow of other colors and along with a fountain pen make a great gift for an artistic friend or a new fountain pen user. The four eyedropper bottles are contained in a 4 5/8" H x 4 1/4" W x 1 3/4" D polypropylene flex-hinge box. Once your starter kit ink collection is all used up these components are all re-useable for future ink mixing projects.
