Thanks For Making A Difference Black Strata Tumbler
* Double wall insulated 16-oz. tumbler keeps beverages hot or cold * Two-tone stainless steel exterior features a shiny chrome top panel and bold metallic-look color panel * Black polypropylene screw-on-slide-lock lid eliminates leaks and spills * Fits most car cup holders
Purchased these as an gift for our graduating volunteer parents who will be moving to middle school. I haven't tried using it but the quality looks good and the people who received it liked it. Not sure if they are spill proof so I may have to test one out and see.
