Investing in a reusable Fressko flask is the smartest choice for your health and lifestyle. Our glass flasks are made from BPA-free, double-walled glass so you’ll never have to worry about chemical leaching, flask or cup discolouring or flavour tainting, like you would with cheaper materials. The same goes with our stainless steel range. Everything is to food grade standards - untainted and safe for your family.

Fressko flasks are made from the highest quality glass, bamboo and stainless steel
