This product’s bottle is made of thick PVC and has good impermeability. When you pour water into the bottle, the screwing lid made of environmentally friendly polypropylene is sturdy, so you don’t have to worry about water overflowing and burning your hands. Furthermore, its smooth surface is gentle for our skin. Notes: Fill the bottle with two-thirds of its capacity when pouring water into it. Please cover the nut after filling it with hot water, but do not tighten it at first. Then squeeze the hot water bottle to remove any remaining air. Please tighten the nut now, but do not overtighten to avoid damage.
