• GL18 Child-Resistant Closure with Tamper-Evident Ring, and Integrated 1.5mm Dosing Plug
  • Amount dispensed is dependent on your specific oil formulation and viscosity
  • 1.5mm is Cannasupplies’ standard size plug. This can be customized for use with larger or smaller sizes; Item # C18D-15-W (1.5mm, white). See Dosing Sizes tab below to learn more

How it works:

  • Once closure is properly applied to the bottle, the tamper-evident ring engages, and integrated dosing plug remains inside the bottle
  • Child-resistant closure is removed using push-down and turn CRC mechanism, integrated plug remains in bottle, and tamper-evident ring breaks upon initial opening
  • 1.5mm dosing plug is ready for use
