Stanley The Iceflow ™ Flip Straw 2.0 Tumbler 0.89L / 30oz Colorful Thermos 0.89 Lt

Hello, The IceFlow Flip Straw 2.0 Tumbler's lid design with a straw has been produced to minimize leakage. When the lid is closed and in the locked position, it does not leak under normal use. However, if the product is completely inverted or kept in a side-lying position for a long time, there may be a slight leakage from the seal area. You can safely choose it for daily carrying and use, it is recommended to hold it upright for the safest use.

Hello, the main body of the product is made of 18/8 high quality stainless steel. The "plastic" designation in the Trendyol system stems from the fact that the lid and straw assembly are made of plastic. Thanks to the steel body, you can use it for both hot and cold beverages. Thank you for choosing us for your shopping. 😊
