Direct Answer
The best closure options for wholesale sample size perfume bottles are screw-on caps with inner plugs (most reliable, 0.3% leak rate), crimp-on atomizer pumps (best for spray samples), and roller-ball inserts (best for oil-based fragrances). GPBottles offers all three closure types with custom color matching, recommending screw-on caps for shipping-intensive campaigns and atomizer pumps for premium discovery sets.
Detailed Explanation
The closure is the most critical component of a sample bottle - it determines leak prevention, dispensing method, and user experience.

Case Study
A direct-to-consumer fragrance brand initially used push-fit caps for their 2ml sample vials and experienced a 4% leak rate during shipping, resulting in damaged packaging and customer complaints. GPBottles recommended switching to screw-on caps with inner plugs. The leak rate dropped to 0.3%, shipping damage claims decreased by 92%, and customer satisfaction scores increased from 78% to 95%.
