    Best Cup EVER!!

    I really REALLY love this cup. It hold all my tea, water, and other drinks I enjoy and it actually fits in my car’s cup holders unlike other cups I’ve tried before. The silicon sleeve helps keep the cup from sliding on the table and countertops and helps protect my hands when I’m drinking something hot. 10/10 totally recommend!

    This makes us SO happy to hear, Karina! Thank you so much for your support :)
