sturdy, BPA-free acrylic tumblers that comes in a set of 4. Also comes with 4 straws and a straw cleaner. Comes in different sizes. I went for the 16oz. I love having these straight tube tumblers at my desk for work. I like the clean, minimalist designs with practical use. I use these for coffee, tea and water mostly and it feels nice in the hand cause it’s a straight tube shaped tumblr. Was looking for these exactly and now I use them daily and gifted some to my family ☺️ It’s always smart to have water in your desk to remind yourself to stay hydrated! 💙 - Amazon office, Amazon finds, minimalist, tumblers, simple cups, acrylic tumbler, 16oz tumblers, home office essentials LTKhome LTKVideo LTKfindsunder50
