Pens with D1 refill
From emboxit
- Does the Pilot Hi-Tec-C Slims refill fit in the Zebra Sharbo X?
- Both of these pens use what is called a D1 size refill, so yes, the Slims refill fits fine in the Sharbo X. Most D1 refills are interchangeable between brands, although the small tolerances might make the fit tighter or looser depending on the pen
