I love everything I ordered from mermaid straw. The only issue I had was the netted paper used to wrap the cup left fibers on the silicon piece on the lid. A little difficult to get off but other than that absolutely loved everything

Beautiful cup - tough design
The cup itself it gorgeous. Love the size. Easy to carry. However, the design could use some work. It took me about 15 minutes (and multiple routes) to unscrew the top. I thought it was a one-time thing, since it was brand new out of the box. Nope. Every time I've used it since, it is near impossible to unscrew. Disappointing. :(

Best cup I own
This cup keeps my ice cold for a long time. I quite enjoy it and would definitely recommend it to others. Thank you so much mermaid straw!! I’ve already made another purchase for a Christmas gift and will be showing up soon. The shipping is great and efficient.
Thank you SO much for your support, Jennifer! We're so glad you love your cup!

Great
Was bigger than I originally thought but love it
It got to the uk a lot quicker than I thought and the shipping wasn’t bad. Will hopefully purchase again sometime
