Fressko's philosophy is simple: be kind to Mother Earth, to others, and to yourself. That's why they designed their Stainless Steel Infuser Bottle, made from BPA-free, insulated, vacuum-sealed food-grade stainless steel with a 2 part stainless steel filter nestled inside to easily infuse your drinks with tea, fruit, coffee, and more. Plus, the leak-proof lid and durable stainless steel body makes it a perfect travel buddy! To use: add loose leaf tea/coffee or a tea-bag to the long filter, screw on the short filter. Pop it in the flask, click into place and add boiling water. For fruit infused water, add fruit to the long filter, click the short infuser into place, fill with icy water and enjoy!
