This is a water bottle from Banco do Brasil, received as a souvenir when I watched samba at the Brazil Pavilion of the Osaka-Kansai Expo. It's made of aluminum and is very light. It does not have heat or cold retention properties. Comes with a carabiner. - Color: Blue - Material: Aluminum - Capacity: 500ml I'm selling it as I don't use it. Thank you for looking.
