I have a few of these, use them as my everyday mop. Have only filled with paint so far (AP MOP 1.0 formula, Junobo and OTR Soultip) no inks. A lot of fun. If you plan on using the 7mm nib be prepared to buy some replacements. Steel roller takes a little getting use to but the longevity is nice. Nibs have the tendency to want to pop out so be careful when opening the cap. All in all great little mop.
This is the sh*t. So glossy . i mixed it with pilot and definetly makes other inks look cheap. I filled up a art primo 8mm marker and it is chuch. Dont sleep on this product. Art primo you guys rock!!!
P.s you guys should open a shop in portland oregon
