MASVIS 30 oz Stainless Steel Vacuum Insulated Tumbler Double Wall Travel Coffee Cup for Cold & Hot Drinks（30oz-4 pack，White）

I started using this mug every day after I received it. I love the color of it. The mug fits into the cup holder of my car perfectly. It is now easy for me to drink water or coffee while driving. The lid helps prevent the liquid from spilling out, while providing a way to allow me to sip on it.

This cup is just what I was looking for! With 2 young children, my coffee never stays hot...until I found this cup! It keeps my coffee hot and my water cold. It’s also huge which is super convenient not having to constantly refill. The color is beautiful. Great quality product!

This works just as I'd want a tumbler to- it has worked to keep my drinks both cold & hot. During the warmer weather, I'd bring it in to work in the morning and it would last well throughout the day and now that it has snowed, I use it to keep my tea warm. I like that there is not an obnoxious logo or anything on it. It's nice a sleek-looking. I do wish it had a closable lid but it hasn't necessarily caused any problems yet- just be aware that it's not a fully enclosed lid (but 100 times better than no lid).

I always carry a tumbler with hot coffee in the morning while driving to work. In the summer I like to fill it with cold drink in the cup holder for road trips. This stylish stainless steel tumbler fits my need for both hot & cold drinks and it's pretty durable & sweat proof. The clear lid can easy tell the level of my drink, it's easy to sip for the hot drink and can also use a straw with any cold drinks, what a clever design.

Have this as a gift to my cousin who drinks smoothies in the morning. This one is big and fits all of her smoothie which she drinks while driving to school. She loves it. It is her favorite color too. I personally feel there should be a sliding cover to close the opening. But it is sturdy.

Love this cup, keeps ice cold and beverage cold aswell. The lid is a little hard to latch but keeps fluid inside the cup.

I needed tumbler that would my hot tea. This did just that, it seems pretty big when you first get it but for me it holds the right amount of liquid. There's an opening that I could put a metal straw in which is a bonus for me.

We have previously purchased over priced stainless steel tumblers. This tumbler keeps our drinks just as hot or cold as our other tumblers did! I like the variety of color options so we know who’s cup is who’s.
