The Signature Set

The Signature set includes the whole Insert range, along with two Blueberry grips. The Blueberry is an ultra-thin roll-on silicone sleeve that changes nothing about how your pen feels, except it enhances your grip. At 0.7mm thick and ~2.5g, it's the closest thing to a bare pen you can get while still having meaningful grip. Use with Korelax Inserts for a fully modular setup. Compatible with 9.5mm diameter pens and up. A sleeve tool is included with every Blueberry for easy fitting and adjustment. Watch the installation video before first use to avoid damage to the grip or your pen. Pen not included.
