GOOM 500ml Portable Stainless Steel Vacuum Insulated Tumbler with Straw, Leak-Proof, and Easy-to-Clean Lid, Includes Strap, and 3-Way Function.

[Safe Materials]: The inner bottle of the cup is made of high-quality stainless steel 316, which is environmentally and health-friendly, while the lid is made of food-grade silicone and PP. Both are BPA-free and protect against the effects of chemicals. *Stainless steel 316 is more corrosion-resistant than the commonly used SUS304 (18-8), and is resistant to salt corrosion and rust, making the inner bottle particularly durable. (Please clean the contents promptly after use, without leaving them lying around.) [3-Way Drinking Spout]: The specially designed drinking spout can be used in a variety of everyday situations. It comes with a straw, allowing you to enjoy the drink slowly while sipping, making it ideal for women who wear lipstick or lip balm. The small drinking spout is perfect for those who don't like hot drinks or have sensitive tongues. It can also be used safely while driving. [Heat & Cold Insulation]: The stainless steel vacuum insulation construction maximizes the ability to maintain the temperature of your drink for a long time. Hot drinks can be kept at the right temperature for over 6 hours, and cold drinks for over 4 hours. This mug is perfect for hot coffee or cold drinks. Even with cold drinks, there's no condensation, so you don't have to wipe off the drops repeatedly. Even with hot drinks, the outside stays cool, making it safe to use. [Easy to Clean]: The large-diameter design of the cup not only fits ice made in a typical household refrigerator's ice maker, but also allows for easy access to the back for thorough cleaning. The interior drains well, so it can always be kept clean. The simple yet easy-to-hold design makes this drink bottle extremely convenient for use in the office or outdoors. [Wide Range of Uses]: This stainless steel 316 coffee tumbler is perfect for a variety of occasions, including outdoors, at home, and in the office. It's perfect for everyday use at home or at work, as well as for travel and business trips. It's also perfect for a variety of outdoor activities, including hiking, fishing, hiking, cycling, camping, and BBQs!
