“These work surprisingly well. I’ve had mine keep an opened drink cold for about two hours and an unopened drink cold most of the day. There’s an inner liner that needs to be removed to hold the larger energy drink cans properly.”
“It’s universal so it will take a 16 oz bottle, 12 oz cans and ect. Keeps drinks just as cool as they were when you put them in hours later. Has a good feel when you hold it and looks great.”
“Have been looking for a cooler for the 16.9 ounce Diet Coke for the last few years. Have had little success and now finally found the PERFECT fit. It fits the 16.9 ounce bottles PERFECT, it looks PERFECT, it fits in cup holders PERFECT and it keeps the liquid cold. PERFECT. Thanks Frost Buddy!”
