If your marker is feeling a bit dry and the color is not quite right, it's time to reach for the Artist Marker Refill by Altenew. The package includes one 30 ml alcohol-based marker refill in Sapphire that can refill your marker up to 10 times and is so easy to use! 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 you're done!
