·REFILLABLE & VISIBLE INK LEVEL: Stay in the flow. The clear ink window shows your ink level at a glance, helping you avoid running out mid-project. Refill anytime with matching 60 ml ink bottles (sold separately). One bottle refills up to 10 markers to help keep colors consistent across multiple pieces and series.

·HIGH OPACITY & STRONG ADHESION: Bold, vibrant color on more surfaces. Ohuhu acrylic paint pens cover well even on dark or black backgrounds, making details stand out with less layering. Once dry, the paint adheres well to rocks, glass, ceramic, plastic, eggs, and more, with a durable finish that resists scratches and helps prevent peeling or flaking.

·2MM ROUND TIP & 6 EXTRA NIBS: One tip for both outlining and filling. The 2mm round nib gives you control for clean lines while still covering larger areas. Six replacement nibs make it easy to swap out worn or dried tips and keep working.

·LONG-LASTING: Cleaner results with less mess. Smooth, consistent flow reduces skipping and blotches. Once dry, the paint is waterproof and lightfast, helping artwork stay bright indoors or outdoors over time.

·PORTABLE BAG & GIFT-READY SET: Easy to store, easy to take. The durable carrying case keeps the acrylic pens organized and ready to grab at home, in class, or on the go. Gift-ready packaging makes it a great pick for artists, hobbyists, students, and DIY crafters.
