If each Flaxie Freeze sold since January 2019 replaced just one disposable freezer bag every month, then together we’ve already prevented more than 2 million pieces of plastic waste. 🙏
Assuming that each of the disposable freezer bags that were replaced by a Flaxie Freeze weighed 5g, we have saved 10 tonnes of plastic waste. 🫶
