Capillary technology that feeds paint through replaceable tips at consistent pressure, eliminating the frustrating sputters and blobs that plague conventional paint markers. Squeeze the barrel to prime the flow, then work smoothly across surfaces from canvas to metal to concrete. Acrylic-hybrid formulation adheres to materials that typically reject paint, glass, plastic, sealed wood, while remaining dilutable with water for controlled washes or acetone for aggressive thinning.

Five tip sizes handle different applications: 1mm for precise lettering, 1.5mm for versatile line work, 2mm for sketching, 4mm for filling, and 15mm for covering large areas. Each tip unscrews for replacement or cleaning, extending marker life significantly beyond disposable alternatives. Patented Flowmaster pump valve controls paint release; internal mixing balls keep pigment suspended during storage. High-opacity coverage means single-coat application over dark surfaces, while UV-resistant formulation prevents fading on outdoor murals and street art.

Refillable design accepts One4All refills in 50 colors. The system transforms expensive disposable markers into permanent studio tools. Street artists, sign painters, and mixed media practitioners value the crossover capability, one marker system that genuinely works across techniques and substrates without requiring different products for different surfaces.
