2支黑色+1支白色巨型丙烯馬克筆，15mm巨型筆尖

The 15mm nib lays down such a thick, smooth line that my coloring pages looked finished in half the time. These markers are seriously permanent—I accidentally got black on my jeans and it survived a full wash cycle.

I was nervous about the water-based ink bleeding through my sketchbook, but it’s completely waterproof once dry. The jumbo tip lays down a thick, even stripe of color in one pass, and the cap snaps shut with a satisfying click.

The 15mm nib is genuinely massive—it laid down a thick, even stripe of white in one pass, no re-dipping needed. I used it to outline a large poster and the ink stayed waterproof even after I accidentally wiped it with a damp cloth. That Italian acrylic ink is the real deal.
