Penbbs is chinese fountain pen forum. It seems the guys are not only talking about pens but also mixing inks and the moment they've created approximnately 200 inks. Wow. I remember I've seen Lgsoltek reviews of their inks and I had a chance to try opuntia Stricta ink that was rather nice in terms of color and quite plesant to use. Recently I've received samples of few other Penbbs inks.
Ink no. 184 (can someone who knows chinese follow the link and translate it to english?) is well behaved yellow ink. It looks rather nice in broad Kaweco nib and the shading potential is strong. The ink isn't crazy wet but neither it's dry. It's pretty well behaved. I believe the sample came from Lgsoltek - thank you
