Nail enamel requires a chemically resistant bottle, a precise neck and a cap brush system that delivers clean pickup and spread. We provide round, square and signature shapes, customize glass tint or frosting and print brand elements for standout displays. Brush options vary by stem length and bristle style to suit treatments or high pigment formulas, and wipers are tuned for controlled payoff and reduced neck mess. We perform fit checks for cap torque and drop testing for pack durability, then pack with separators to avoid scuffing. Coordinated cartons and case counts are planned for salon distribution, retail and e commerce fulfillment.
