Fineliner Color Pen Set 0.38mm Fiber Nibs Colored Fine Line Point Assorted Colors, Pack of 10

Can these be used on canvas?

Can I order your sipa sr153 0.38mm in just tree colors red blue and black?

I’m only interested in buying all pink pens! Is there a way I can request and pay more? $20 for a 5 pack?

Do the pens smudge with water?
