2 Pack Reusable Neoprene Coffee Cup Sleeves - Insulated Cup Cover Holder for 30oz Starbucks Tumbler & Dunkin' Donuts Large Cups (Black) - Perfect for Iced Coffee, Hot Drinks & Travel Mugs - Keep Hands Cool & Drinks at Ideal Temperature

The concept is great, but for something that was supposed to fit the large cups from Dunkin it falls flat. It won't completely fit the cup so it's easy to tip since there's a good half inch of loose neoprene at the bottom of the the cup since it won't go all the way to the top of the up.These do not fit a McDonald’s/fast food large cup like I had hoped but I’ve made them work as needed. They keep drinks cool and work on my stainless steel cup!Very Handy : ) and just as you see it in the pics! I took off one star because you have to hang it somewhere to air out for a week! Toxic smell was really strong. You could just throw it in the washing machine on a gentle cycle zipped up in a laundry mesh bag for delicates as an option. Still worth it for how cute and handy it is. Just stay away from the smell! . . . . : (If it was stable at the bottom, it would be perfect. Soooo pretty and happy!These are super cute and durable. I especially love the added handle. Easy to clean. Only downside is that they are too tall. Both sizes are too long for any cup i use, causing it to push the lid up. I have to scrunch it down on the bottom to make it fit which then causes it to sit unstable. Great idea....wrong size.This neoprene sleeve fits my 24 oz. Bubba insulated cup pretty well, except for being a bit short. It is not shaped to fit a larger fast food cup, as it does not have the smaller lower portion like the competitor, Java Sok. I have a form-fitting Java Sok from McDonald's that I love. So, other than the fit/size, how does this compare to the Java Sok? The material feels okay though it does feel as though it is lighter and thinner. I do like the added handle on this sleeve. The pattern I received is also okay, as is most of the construction (the handle is simply cut neoprene with no edge stitching). So, why the one star rating? Well, like most folks, my nose is near my mouth and I cannot use this sleeve without smelling the foul odor of the material it is made from. With every sip I take, I am confronted with the overpowering odor. I find it unpleasant and it even makes my hands stink after touching the sleeve. I really tried to like this product, but the smell is just too unpleasant. I have tried washing it, soaking it in sanitizing solution, soaking it in baking soda water, washing again, and still it stinks. Since it smells so unpleasant, I cannot use it for its intended purpose.These are ok. Not meant for using heat transfer on. Both of mine got ruined and I had the poly setting and used wax paper as well. As far as the actual product, they are ok. Not the best but ok.love using these for loaded teas and iced coffee!
