Frost Buddy is a small business that specializes in universal thermal-controlling drinkware.
Check out a TikTok of the Frostbuddy in action.
It’s designed to fit small, medium, and large sizes in most major coffee chains, including Starbucks, Dunkin’, and McDonald’s, so it’s worth the investment! It even comes with a lid, so you can use this for hot drinks as well!
Promising review: “I absolutely love this! I use this all the time for my coffee from Starbucks, and it is amazing! I’ll get iced coffee at 9 a.m. and still have ice in it at 7 p.m. I have many Frost Buddy products now, and their entire line is phenomenal. This is definitely a must-have item for coffee or tea drinkers. I love that it also comes with a leakproof lid, so you can put your own drink in there, too. Overall, awesome product!” —EHW
