Built-in Stainless Steel Band – All-in-One, screws directly onto the jar!
Made of 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.
Dishwasher safe – just throw them in the dishwasher along with the Mason jars (and hopefully the reusable straws too).
