Guide to filling your hot water bottle

Untie the velvet ribbon on your silk hot water bottle cover and open the cover at the top and unscrew the cap lid.
Heat up a kettle and let it cool down for 5 minutes, before filling up your hot water bottle. Be careful not to use boiling water as it can damage the seams of your bottle and add to the risk of burns.
Slowly squeeze the remaining air out of your bottle so that the level of water rises to just below the top.
Screw back the cap lid tightly and close your silk hot water bottle cover and tie the velvet ribbon again.
