COPIC Ciao markers are versatile double-ended refillable markers with fast-drying, permanent non-toxic ink. Ciao are the perfect markers for beginners. They have the same ease of use and special features of the COPIC Sketch marker, with a super brush nib and a medium broad nib, yet it has a round barrel and comes in a convenient small size that makes it perfect for young artists. Both nibs are replaceable.
