But the cozy to help my husband from breaking any more mugs! He likes drinking out of the ceramic ones and they kept slipping out of his hand. This cozy fit perfectly.Keeps my iced coffee cold. No condensation build up. Grip is great. No complaints from me. The large fits my Dunkin donuts iced coffee perfectly.My Husband loves this. Keeps ice cold drinks colder longer, or hot drinks (like coffee) hot longer. Either way it’s a win win.Love it ! Way cheaper then the Java sock. The large one fits the large Dunkin’ iced coffee cups beautifullyNice quality, but package is labeled wrong and I received a multi-color pack twice. Sent both back with explanation on my return both times.Doesnt fit my 16-18-22 oz reusable plastic cups it too large.At first l liked the protect but after awhile the bottom falls apart.Does exactly what it’s supposed to do. It actually fits several different cup sizes. Not only does it keep the cup from being too hot to hold with hot beverage, it has an insulating material that helps keep hot drink hot longer and cold drinks cold longer. It also keeps the cup from sweating. These are nicer than the average rubbery ones because these are nice and thick and can actually insulate the cup.these are greati have a few cups that i have carboard sleeves for, i wanted something that i didnt have to keep replacing due to the enviroment, these are not the 1st sleeves i have tried , they are though the sleeves i have the best feel with, although the pink ones for the wife went out of stock (hopefully i can get them if they come back in stock).
