Sakura XPSKA-49 PenTouch Permanent Paint Marker, Low Odor, Xylene-Free, 0.7 mm Extra Fine Tip, 141 mm Size, Black

Should buy if a glass artist

I used it for my anime glass painting and it's pretty good except that you have to double coat the lines or else the lines will cracked (you can see the crack lines from the first image, around her lower mouth). It's a little expensive with the shipping fees but I'll say it is worth it :)

Cero recomendable, se le sale toda la tinta, muy mal producto!

Excellent pen, the weight of the paint was perfect for our project. Writes on materials that regular calligraphy pens do not. Nice rich color. however, be aware that this pen is thin.

I used this paint pen to paint wine glasses for my family for christmas and it was great!! Easy to write out words and script, not messy at all, and ink lasts a longer time than other paint pens I have bought in the past! Would recommend to anyone!

Writes very smoothly. Ink flows nicely. Doesnt skip when writing. The nib is on the thicker side, so if you're looking to do fine line work this is probably not the pen for you.

I was having issues writing on metal and it running once I sprayed a clear top-coat enamel... This is the answer for stay power<3 I really want to remove THAT label though!
