Writes very nicely. Filling mechanism works great. If you’re not familiar with a vacuum filler, definitely look up pilot 823 videos for tips. Nib is smooth with very wet ink flow. Only complaint is the frosted black finish makes the cap threads feel a little different so i worry that it’s not tight enough but it hasn’t dried out or anything yet so not a problem. Size is good—very similar to my 823—and noodlers rose coral looks really nice sloshing around inside the barrel.
