Kuretake Tegami Refillable Letter Pen - Super Fine Lettering Tip - Black Body

i LOVE love love this pen! even when scribbling notes, it makes my handwriting so beautiful! the Tegami ink is NOT waterproof; and it also takes a few seconds to dry. it WILL smear.

it looks like the CocoIro refills are the same as the Tegami refills (same nib), but i don't know if the CocoIro ink is the identical formulation.

i bought the black enamel one, and was dismayed that bits of the enamel chipped off (on the butt-end, where the cap would fit while in use). still, i LOVE this pen! i'm considering getting a silver one, which presumably won't have this chipping problem.

Anyone know if the ink is waterproof or smear proof?

I love this pen. I can really press down on it to get thick lines without worry. When I replace the cartridge, I will also be replacing the point. I am anxiously awaiting running out the lettering tip so I can try the brush pen tip!
