Paramedics, police, fire-fighters and social services know to look in the fridge when they see the Message in a Bottle stickers.
This can be really helpful if the person you care for has a condition that can suddenly change so that they need medical help; such as diabetes or allergies.
The Message in a Bottle scheme is run across the UK by Lions Clubs.
Your GP or pharmacist may be able to give you one of the bottles or you can contact Lions directly.
