What is the NFC function??

Thank you for the great question! Each Ocean Bottle is equipped with an NFC chip at its base. NFC is the same harmless technology which you will find in contactless payment cards, hotel room keys, office badges etc. We are building a platform which will enable you to fund more plastic collection impact when you tap your Ocean Bottle at a partner location around you. Today if you tap your Ocean Bottle onto an NFC activated smartphone, it will lead you to a webapp where you can register your Ocean Bottle to your name and find refill locations around you.

What is the diameter of the bottom of bottle please? I need to check it fits in my car bottle holder. Not all ‘standard’ bottles do.

The diameter of the base is 68mm (6.8cm)

How many hrs keep cold and hot? Basic details missing in the description

Hi Andrew, Thanks for asking! The bottle can keep the water cold for up to 18 hours. And it will keep the liquid hot for up to 9 hours (it should hold water above 40 degrees after 9 hours). Best regards, Ocean Bottle Team

Is the capacity 500 ml to the larger opening, or 500 ml to the top opening?

Hi Lavinia, Thanks for asking! The capacity of the entire bottle to the top opening is 500 ml, metal flask volume is 450 ml. Best regards, Ocean Bottle Team
