Ozark Trail 18 oz Vacuum-Insulated Stainless-Steel Tumbler with Handle, Papyrus Beige

Cup is awesome for keeping cold drinks cold! I got it for my mom, who's an ice'aholic... she and I both were VERY impressed at the functionality of this tumbler. We're in FL (temp at time was 84°F), and left the cup in the car for about 4 hours. When we came back to the car, she still had ice and ice cold coca cola! She was overjoyed (and so we're we). Usually we have to turn on a separate ice maker just for her use, but not worth her using this cup. She wasn't a 24 oz now that she knows it works so well! It also doesn't leak if filled with water and using the included straw, which is great. However, because she wanted to use soft drinks in this cup, we had to use a regular straw because with the included straw, the acid kept pulling it up into the straw and running out. This has been one of the best $8 investments we've made.
