These Straw Hole Tumbler Lids are made of 18/8 304 grade stainless steel. Stainless Steel is one of the most commonly used materials in the kitchen, used to make cookware, utensils, commercial food processing and storage equipment, and more. Stainless steel will not leach any chemicals into your beverage like plastic can, and it is safe for use with all foods and beverages.
The 10mm straw hole will work with most of our straw options, and includes a silicone grommet with plug for stashing in your bag while on the move. If you use Mason jars for drinking every day like we do, you need a supply of high quality straw hole lids. These lids are made to last!
