Simply fill with cold water to enjoy instant coolness and relief from warm weather. - Directions for use: Hold the hot water bottle around the neck in an upright position. Twist open the stopper and carefully fill up the bottle two-thirds of capacity or less, with hot or warm water. Screw the stopper sufficiently tight to ensure there is no leakage. Check that the funnel is empty to prevent burns. DO NOT overfill. DO NOT use boiling water or water from a domestic hot water system. DO NOT sit on a filled hot water bottle. When not in use, drain completely and keep the stopper removed, in a cool, dry dark place with nothing on top of it. Prevent exposure to sunlight. This will assist with the life of the hot water bottle. - Specifications:Dimensions: 36cm x 23cm x 4cm (unfilled, with cover on)Capacity: 2 Litre - Weight: 410g (with cover on)Designed in Australia, Made in China. - Materials: Polyester Boucle outer / Polyester Suedette Lining. 2L Rubber Insert. - Conforms with the British Standards 1970:2012.
