A compact coiled pen holder that clips onto notebooks, planners, or clipboards to keep a pen within reach. The stainless steel coil stretches to grip the pen as it's inserted, then retracts to hold it snugly in place — no separate loop or strap needed.

The coil's inner diameter is about 7mm at rest, expanding to roughly 15mm, so it fits most standard pens and pencils. Made in Japan.
