Yes, our 40oz Vacuum Insulation Tumbler is crafted from high-quality, food-grade 18/8 stainless steel. It is 100% BPA-free, rust-resistant, and does not retain odors or metallic tastes.

Yes, despite its large 40oz capacity, the tumbler is designed with a tapered base that fits securely in most standard vehicle cup holders, making it ideal for daily commutes and road trips.
