300 ml bottles are handy and can be offered in meetings, conferences, buffet dinners, lunch spreads, corporate get-togethers, weddings, special occasions, etc. These are very hygienic options as each individual can be offered a bottle each. These are made from high quality food grade plastics that enable them to store water for longer hours. 300 ml bottles are easy to carry and can be disposed off quickly as the water quantity is apt for a single individual. Caterers mostly prefer these bottles.
