That's amazing to hear, thanks so much Zyrah!!
I needed to be motivated to drink water. My new mermaid meets the need. Mahalo. I love it.
Love this cup
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 :)
This cups is so pretty and is the perfect water cup for me for work!
