Another problem I have with the grip section material (and this is a big one) is how it stained immediately when I submerged the nib and section into an ink bottle. This is usually no big deal, right? Just wipe away the excess ink after you fill it and you're good to go. With the Monami, the lowest part of the section that was submerged in the ink still has an obvious blue-green stain from the Iroshizuku syo-ro ink I used. To be fair, syo-ro is a really gentle ink and I've never had any staining issues with it before. I think this is directly due to the material and finish that Monami used on the grip section. Thank goodness I didn't dip the section any further into the bottle, or it would be an even bigger stain! I'm sure I could remove the stain with some rubbing alcohol or some other kind of cleaner, but that's really difficult to do when there's ink in the pen. It's so close to the section and nearly impossible to clean without more ink spilling out onto the rag or whatever I use to clean it. This is frustrating, but the pen is still completely usable. I should experiment with other inks to see if they also stain the section, but I'm not sure it's worth it. It's already stained now, so what does it matter?
Moving down to another positive attribute of this pen: the nib! The steel nib is an EF and writes beautifully. It makes a small mark without being scratching, and the ink flow is perfect. There's a Monami brand and some minimal decoration stamped onto the nib, along with an "EF" to indicate the tip size. Unfortunately, EF is the only nib option for this pen.
I've really enjoyed writing with this pen. The size and weight are perfect for my hand, and the tactile grip section is great at providing grip without getting slippery after a few moments of use. I love how the cap always lines up with the body when capped or posted, and I love the lines that run up and down the body to create some visual interest on an otherwise plain pen.
