These plastic sleeves fit around and shrink to seal any bottle with a neck size between 16mm and 22mm in diameter. This seal provides proof that the bottle hasn't been tampered with and thus that the product within is exactly what was purchased. They have an easily torn strip built into them to help unseal the bottle which remains intact throughout the heat shrink process.

The initial dimensions of one side of the seal are: 43mm long, 24mm high
Please choose clear or white from the options offered.  Styles vary slightly.
