Col-O-Ring Ink Testing Book

This booklet is the perfect tool for testing and cataloging your ink collection. We love using it in the store!
In stock

The paper—made by a 400-year-old European mill—was rigorously tested to ensure that inks would not feather, bleed, or show through. The paper is lightly textured and safe for use with even the sharpest nibs. The paper is protected by sturdy chipboard covers with stylish letterpress printing and held together by a handy binder ring, letting you remove and reorganize the sheets whenever you want.

Thick, ink-friendly 100 lb (160 gsm) acid-free paper with a slightly toothy texture.
