Effects: Relieves pain resulting from muscle contractions, neck stiffness, arthritis, cramps, or menstrual pain. Features: It consists of a natural rubber reservoir with a capacity of 2 liters. Its covering is made of very soft and comfortable mesh. Dimensions: 33 x 20 cm. Instructions: Unscrew the sealing cap, hold the bottle by the neck, keeping it upright, and carefully pour hot water into it, avoiding burns caused by air bubbles that may form. Do not exceed 2/3 of the total capacity. Remove the air from inside the bottle by lowering it onto a flat surface until the water appears at the opening, ensuring correct positioning. Make sure the cap is securely closed to prevent leaks.
