Universal Iced Coffee Sleeve - Insulated Double Wall Reusable Stainless Steel Holder Sleeves Insulator for Cold Drinks Fits Starbucks Dunkin Donuts Dutch Bros Small Medium Large Cups (Black)

This worked great. I bought a small iced coffee from DD, and it stayed ice cold with no ice melting, for over 4 hours. And I was outside in the heat all day. I was doing chores around the yard, so I would take sips here and there. No watered down iced coffee from melting ice. Just ice cold. I took the cup out to feel the inside of the cup and it was very cold. So it held the temperature perfectly.

I just got this and used it yesterday w/ my Starbucks iced energy drink - this works so very well and I had fully formed ice in my drink the entire several hours it took me to drink it - only because I set it down somewhere in the house and forgot about it until a few hours later- it was one of those days...I love this tumbler / iced coffee sleeve...except 1 small thing which doesn't detract from my 5 star rating because it has simply to do w/ my small hands - they get very tired holding this without a handle, so I purchased 5 different handle options and found one that works perfectly for me, so now I have the option of using w/ or w/out a handle. Also the black leopard pattern is really pretty!

Great tumbler that kept my ice coffee cold for hours. The ice hardly melted! My one criticism is that it only fits the large dunkin cups. Medium and small fall into the tumbler too far.

This cup is so amazing, it keeps ice in my cup overnight. No leaks

Keeps my Starbucks cold for more than 10 hours. LOVE IT!!!
