20ml amber roller bottle wholesale

Wholesale sourcing of 20ml amber roller bottles involves securing a consistent amber glass format for fragrance or oil-based fills at volume. Amber glass is often chosen to reduce light exposure, and buyers should confirm the exact glass color and surface with samples, since tone can vary. Key specification points include bottle capacity, neck finish, roller type, and cap material, along with the fitment between roller, bottle, and cap. Decoration, carton packing, and labeling requirements should be agreed before production, and sealing performance checked on assembled samples to avoid leakage during storage or transit.
