Sakura Gelly Roll - Medium Point - White (Opaque)
Sakura spent the better part of five years perfecting this very difficult product. While competitor's white gel inks are prone to clog quickly after initial use, Sakura has figured out a way to keep the ink flowing.
Remember to replace the cap on the pen when not in use. Not intended as a "correction fluid" pen.
Meets ACMI non-toxicity standards.
