Of COURSE you’re not a bother, gooossssh! Aaaah, thank you ;o;! I’m glad you like my lines! As for my pens, well, there are three I use frequently: Prismacolor Premier: Brush Tip Marker (B), Koi Coloring Brush Pen, and the third is Pentel’s Tradio Stylo TRJ50 2H.
The further one in the back of both pictures is the Pentel pen, and it’s actually a fountain pen! They’re tougher to use at first (and still are… but I like the results!), but definitely worth the hassle. And about $10.
Just keep in mind these don’t dry very very fast, especially the Pentel one, and by that I mean that they take a heavy-inked picture about 5 mins to dry completely (ready for erasing sketch).
Thank you for your question! *u*
