Tri Blend Light Yellow Markers by Spectrum Noir from Crafter's Companion! This pen contains three ready-to-blend colors in soft yellow shades that are alcohol pens for seamless coloring! Inside each marker, there are three separate ink chambers, each feeding through to a fine-bullet nib, so you can experience three colors inside a single alcohol marker for the first time. Because they're transparent alcohol-based inks, it's easy to blend from lights to darks without overlap marks and the pens are refillable.
