Excellent refill. Uni-ball Jetstream ink is put into the ballpoint. Note that,
Jetstream ink contains check fraud protection without ISO 12757-2 certification,
as per Uni-ball's website. I submerged a sheet of paper with a written sample
in alcohol, bleach, and boiling hot water: the tests passed and the ink
remained. We need D1 refills now.
