      The cup is beautiful! It keeps drinks cold for a long time. I get so many compliments on this cup!

      So gorgeous!

      Even prettier in person! Love this cup!

      This is just so pretty!

      Watching the videos I was mes-mermaid-ized 😄 by the shimmering colors of the Mermaid Cup and knew I had to get one. It is even MORE beautiful in person and is now the crown jewel of my new eco-friendly cup/bottle collection! What a great size and love the straw opening 'cushion' built in!

      Tracy, we LOVE to hear this! We are so happy to hear how much you love your new Mermaid cup! :)

      Very pretty cup, but….

      I ordered the blue one first since is was the only color in stock so I was very excited when I got the email when the mermaid color was in stock. I will say I love how pretty the cup is. The picture online doesn’t do it justice. I use both cups everyday and find I drink more water since I started using them. They keep my water cold all day and I sometimes have ice still left the next morning. The only reason I am not giving this cup 5 stars is because the paint rubbed off the lid after the first time washing the cup (and yes I only hand wash them). I was very upset and disappointed. The blue hasn’t done that at all and I’ve had it several weeks longer.
