Hello � � Our bottles are produced from number 1 PET raw material. Although this material is generally known as disposable, our products are thick and sturdy, so you can prepare your healthy drinks at home and use them many times. � � Our suggestion: After each use, wash it by hand with warm water and soap and reuse it. � � High heat resistance for long-term use (boiling water, dishwasher, etc.). Not exposing it prolongs the life of the product. So you can easily use it repeatedly for daily detox, smoothies, juices, � � ✨
