    Absolutely stunning

    I love my mermaid cup, I ordered the oops products and I don’t understand why it never made the cut because it is absolutely perfect. The ice in my cup stays frozen all night long. Definitely buy more for myself and for gifts.

    Thank you for your lovely review! We're so glad you love your Mermaid Straw Cups!


    I literally cannot say enough good things about this cup. I grabbed 2 during the Oops Sale and they're flawless. I see absolutely no reason to be considered an oops and it keeps my water cold for ages! 10/10 highly recommend!

    Thank you for your review! We're so glad you love our Mermaid Straw Cups!

    Extremely Happy!!

    I love all your products. I bought enough cups for everyone in my house, and they all love them.

    Thank you for your kind words! We're so happy to hear that our cups are pleasing to you and your family.

    Love my cup!

    Got this cup as well as a straw and some silverware as part of their “seconds” sale but I don’t see a single flaw in any of the items! They all arrived fast and look perfect. Used the cup for the first time this weekend and it actually kept my water cold for a long time! I refilled it 3-4 times before the ice I added in the beginning melted! Very happy with my purchase.

    Thank you for your review! We're so happy to hear that you love your Mermaid Straw Cups and appreciate the quality and speedy delivery!
