Scraping Plug

Supports three mainstream sizes: 18mm, 20mm and 24mm, perfectly compatible with corresponding essential oil bottle mouths and matched dropper assemblies, meeting the assembly requirements of most conventional dropper packaging sets.

Acts as a buffer spacer during dropper installation to avoid rigid collision between components. It forms a tight compression fit after assembly to fill gaps effectively and significantly boost overall sealing performance.

Fills the clearance between the dropper and bottle neck to stop liquid seepage when the bottle is tilted or inverted. It also reduces volatilization of essential oil ingredients and maintains long-term stability of contents.
