Frequently Asked Questions

AI
Always check the stopper for a tight seal and avoid overfilling the bottle; leave a small amount of air at the top to allow for expansion. Regularly inspect the rubber for signs of wear.
It is generally safer to use hot, not boiling, water. Boiling water can put excessive stress on the rubber and increase the risk of burns if the bottle leaks or bursts.
Covers protect your skin from direct heat, preventing burns, and help the bottle retain warmth for a longer period while adding a soft, comfortable texture.
