Continue to create delicious designs with the Altenew Artist Marker Refill in Dark Chocolate! The package includes one 30 ml alcohol-based marker refill that contains enough ink for 10 refills. You'll love how easy it is to use, too! Just remove the brush nib with a pair of tweezers, position the tip of the refill bottle right above the open barrel of the marker and fill the marker with 8-10 drops. Reinsert the old nib or replace with a new nib and that's it.
