Care & Use Tips (to Preserve the Magic)

A few simple habits will help your bottle shine longer:

• Always hand wash using warm water and gentle soap (before first use and after every use)
• To trigger the colour shift, use ice-cold liquids - the colder the better
• Keep out of direct sunlight when storing; UV can fade the special finish
• Avoid filling with liquids hotter than 65?°C / 150?°F
• If you must use warmer drinks, use gloves or a cloth - and be cautious of hot surfaces
• Let all parts (lids, straws, etc.) air dry fully before reassembling or storing
