Sweetener free, not taste free! Perfectly flavoured with the right balance of two favourite mints, organic Peppermint and Spearmint essential oils, with Australian native Peppermint Gum, it is a favourite for both kids and adults. Each refill pack contains approximately 500 brushes, which is the same amount of toothpaste as 6.25 medium-sized plastic toothpaste tubes (and prevents landfill waste!)
