The Uni SXR-80-38 is the 0.38 mm version of the popular Jetstream D1 pen refill. It uses hybrid ink, which is basically modern ballpoint ink.
The refill is also sold in 0.5 mm, 0.7 mm, and 1.0 mm sizes.
The high-end version of this refill is the Uni SXR-200-50. It has a metal body and the same ink. The SXR-200 line is not sold in a 0.38 mm size, so the 0.5 mm is the closest available.
