Through the movement "Bring Your Tumbler, Be an Eco-Warrior" which has been established since 2015 until now, always trying to actualize the use of tumblers for our lives and the environment both in terms of, benefits, trends and uniqueness. One effective way to actualize this is by spreading the 'virus' of the tumbler among young people in Bali in particular. It is hoped that by holding this activity, the most important message, namely the use of a tumbler that is simple but can have a tremendous impact on the earth, can be conveyed to the wider community.
