Assure the best fit

  • The design of the bottle neck is such that there should be a gap (see picture below) between the glass bottle body and the plastic screw ring.
  • If you feel some resistance when assembling the screw ring to the bottle, please stop screw ing any further. The bottle is screwed tight enough.
  • Please do not over-tighten the screw ring. When over-tighten the screw ring, you might damage the plastic screw thread.
