The BilletSPIN Fusion Pen
Where Innovation Meets Obsession
Watch this important video BEFORE ordering any Fusion pen.
The Fusion will be available for Energel, Pilot G2, and Parker style refills. Each refill model uses it’s own nose cap and spring, the rest of the pen is identical. Eventually we will have all nose caps and springs available separately.
Today’s drop is for the Pilot G2 only.
These will show as SOLD OUT until the sale goes live at noon Central on August 5th. This is a 2 minute pre-order sale between 12:00 and 12:02 pm.
You must be checked out before 12:02 pm!!
Please note: Pre-order items may require up to 2 months for shipment after your order is placed.
The BilletSPIN Fusion is the culmination of years of listening to the pen community. It was a long list: Able to accept full length Pilot G2 refills, no rattle, high fidget factor with audible clicks, no tip wiggle and great balance. This model checks all the boxes. Designed from the ground up around an all-new proprietary mechanism by Rich Stadler, the Fusion delivers a writing and tactile experience unlike anything that has come before.
At the heart of the Fusion is a revolutionary mechanism that provides a crisp, satisfying click with every actuation. Smooth, precise, and incredibly addictive, every movement is engineered to inspire confidence while standing up to a lifetime of daily use. Extensive prototype testing through well over 100,000 cycles proved the mechanism's durability and reliability, ensuring your pen performs as flawlessly years from now as it does on day one.
