Show your school spirit by taking this 40 oz. tumbler with you anywhere. This large travel mug made of stainless steel features double walled vacuum insulation and a solid ergonomic handle, allowing for fewer refills on the go. The sophisticated lid, which can be used by either left- or right-handed people, has a straw opening that is splash-proof thanks to a seal that keeps the straw in place. It fits in any standard cup holder with a 3" diameter bottom. This product is free of BPA, phthalates, lead, and toxins. These are made of FDA-approved food-grade stainless steel and comply with California Proposition 65.
