Best fountain pen I own

"I have tried many fountain pens, and the Muji fountain pen and ink cartridges are my favorite. The pen is reliable where the others are not, and writes like a dream. The nib doesn't get clogged, the seams don't leak, and replacing the cartridge is simple. I wish I had tried the Muji fountain pen before buying my $80 fountain pen. I could have saved the money and stocked up on cartridges instead."
