These portable stamps make it easy to add a touch of whimsy to your notebook wherever you go!
Made in collaboration with Japanese artist Eric Small Things, this stamp is actually a set of four stamps stacked together.
The stamps can be separated with a simple twist and pull. Each stack is small enough to fit easily in a pen case, and even comes with a small clip for attaching to a notebook or pocket instead.
The stamps create marks approximately 1 cm x 1 cm, and they feature waterproof, oil-based ink.
