Guru Gettings is an Affiliate for VibesUP. This simply means that we sell their products for them. We did not create these products. The following is the product description pulled from the Vibes Up site.: 
 
27 oz water bottle. 
Stainless steel is a safe option when it comes to using with food and beverage, as there are no chemicals that can migrate into your food from this product.
Please make note that, while the larger of the two bottles is insulated, its purpose is to help maintain the temperature of COLD beverages.
We recommend that you DO NOT use this product for hot beverages as the bottle may heat to an uncomfortable degree.
