The double brush tip design adapts to intricate details, smooth line work, bold color fills, and layered shading, eliminating the need for multiple tools. The high-pigment acrylic ink delivers vivid, opaque color with strong coverage—even on dark surfaces—while drying quickly to form a waterproof film that resists smudging, fading, and peeling. Whether you re decorating rocks, customizing fabric, or embellishing glassware, these dual tip acrylic pens blend versatility, vibrant color, and reliable performance.
