I ordered this solely because it was black (which is my favorite color) I didn’t even pay attention that it was a skinny, so I was a little miffed upon arrival. I’m happy to say this is an amazing cup, and will keep drinks cold literally all day!
I loved my first Siren tumbler so I decided to have another one. They really do keep my drink cold & hot. Depending on what I’m drinking at the time. It’s the only tumblers I use! Go ahead & treat yourself! You won’t regret it! 🖤
I love my tumbler and straw it’s the most amazing thing🥰
My husband has been super supportive of switching to the mermaid straws and has liked my cup, but he wanted the tumbler. So I finally got him one. He is someone who would dirty up 5 glasses a day with different beverages, now he uses just this all day. Saves me dishes. But it also works to keep his drink cold or hot through a work day. He loves it!
It’s my favorite cup. I used for water perfect size to bring in the car for your cup holder. Love love it..
