This is the official Arrtx link for the Oros 90 set I used throughout my 2026 new journal setup. The set feels thoughtfully designed—from the stand-style box to the included coloring sheet—and the blending is the real star. I used them for my big titles and shading because the ink dries quickly and doesn’t leave blotches.
