The Pilot BLGS is a family of rollerball refills that are most commonly seen in the Pilot Timeline pens. These looks like short Pilot G2-style refills and are sold in 0.5 mm — the BLGS-5 — and 0.7 mm — the BLGS-7 — sizes. There is no 1.0 mm size available.
These refill size is interchangeable with Pilot’s Dr. Grip-sized refills, like the BRF and BRFN lines.
