Half Ring

The Half Ring targets one finger. It wraps halfway around the pen and holds that finger in place while everything else stays free. Light-weight, discreet, and effective for such a small insert. Mix and match with other inserts to target every finger differently. Compatible with the Blueberry grip. Attaches and detaches to your pen in seconds. No tools or adhesives required. Watch the installation video before first use to avoid damage to the insert or your pen. Pen not included.
