The Boccsty Stainless Steel Tumblers with Straw are made of premium 18/8 food-grade metal, ensuring durability and safety. These tumblers feature a double-walled vacuum insulation design that keeps your beverages hot for up to 8 hours and cold for up to 10 hours. The non-sweat design prevents condensation from forming on the surface, keeping your hand dry and providing a non-slip grip.

The tumblers come in two sizes: 30 oz and 40 oz, making them suitable for a variety of needs. They are cupholder-friendly, with a narrow bottom and a wide mouth that fits most car cup holders. Additionally, they come with a handle and a reusable straw, making them more portable and convenient to use.

These tumblers are an excellent choice for gifts, suitable for teachers, doctors, drivers, or anyone who needs to stay hydrated on the go. They make great gifts for occasions such as Father's Day, Christmas, Thanksgiving, and Easter.

One of the key features of these tumblers is that they are dishwasher-safe, including the lids, making cleaning a breeze. This saves you time and effort, allowing you to spend less time cleaning and more time enjoying your beverages.

The Boccsty Insulated Cups are versatile and can be used for a variety of purposes, including commuting, road trips, vacations, daycare, home, school, youth sports, picnics, field trips, and birthday gifts. They are the perfect choice for those who need to stay hydrated throughout their daily activities.

When using these tumblers, it's important to follow the instructions carefully. The handle was not pre-installed when the tumbler was received, but a free screwdriver and accessories were provided for easy self-installation. Additionally, it's important to use a straw and to ensure the water temperature is less than 60°C to avoid burns.

It's strictly forbidden to place the products in bright fire, microwave ovens, induction cookers, or dishwashers. Additionally, it's important to avoid adding dried ice, carbonated beverages, soy sauce, soup, or liquids containing alkaline and acidic ingredients to the tumbler to prevent corrosion of the cup body.

When cleaning the tumblers, it's recommended to use a neutral detergent and water. Avoid using alkaline bleach, chemical cloths, or other cleaning agents that could potentially damage the tumbler.

Overall, the Boccsty Stainless Steel Tumblers with Straw are a high-quality, durable, and versatile choice for anyone who needs to stay hydrated on the go. With their long-lasting temperature retention, cupholder-friendly design, and easy cleaning, they are the perfect companion for your daily activities and adventures.
