Nail polish bottles with brush caps are supplied as integrated units for efficient filling and application. The brush cap combines the closure and applicator, requiring precise dimensional matching with the bottle neck to prevent leakage and ensure smooth brush insertion. Wholesale sourcing of these components involves evaluating the brush material (usually nylon or natural bristles), cap design, and neck finish compatibility. The bottle capacity and shape can vary to suit different product lines. Buyers should test the assembled unit for seal integrity, brush performance, and chemical resistance with the intended nail polish formula.
