Mr Hobbyยฎ Hobby Gundam MarkerGM01 GUNDAM MARKERย PANEL LINE PENย BLACK COLOR The Gundam Marker for shading is designed to finish up the model to make it look more "mecha" like, a super fine marker for inking groove lines. As it uses a slow drying ink, mistakes can be easily fixed, and able to use an eraser/rubber to remove overflows. Plus, it stays on very well, so it is easy to use! โ ๏ธ KEEP OUT OF REACH OF CHILDREN UNDER 8 YEARS...
