20mm WHITE SLEEVE VIAL STOPPERS
Isoprene

Eliminates the need for vial crimpers or vial seals!
Insert the narrow end of the sleeve stopper completely down into any 20mm crimp finish serum vials using a downward twisting motion (moisten if necessary).
Once completely inserted, unroll the larger diameter half down around the serum vial neck as shown on the amber serum vial  An airtight, secure fit is achieved without the need for separate seals, stoppers or vial crimpers!
Made of white isoprene rubber.
