and this is my second one I like frozen coffee and I got that little 20 oz blender thing you put it in that cup of most things like that sleeve and you just put your stuff in there and you twist it up I love frozen coffee so my other one was getting wore out so this is why I bought a new one and I really like this one and even I bought some glasses they look like beer cans I bought a koozie for beers it would not fit I can take this one the old one that I have is blue and I slid it up the glasses too long but I could scrunch it down where it was and it sit around that big glass that is like a beer can it's a 12 oz I reckon and it wouldn't even fit the Koozie I bought that's for beer cans you know and you're not getting the Slender ones now this is a slender Koozie but it fits my blender I don't know what you call attachment that I make my frozen coffee in and like I said the other one's getting wore out some so I bought a new one and I can use the old one when I'm ready to use my glasses that are shaped like beer cans I got them on Amazon it has a wooden lid with glass straws if you like to look those up it's not their own Amazon maybe you want to pull your beer into them but I hope you can find a koozie to fit them if not you can get this one at first it might be a little tight but they stretch after a while cuz I had a little bit of trouble getting it on yesterday just a tad but my hands and fingers don't work too good cuz my wrist crushed from a wreck from an idiot that did a stop roll anyway rules were made to be followed to keep us safe because they saw things over and over happen that's why they make rules just like fire safety rules okay be safe on the road and follow the rules don't make a habit of a stop role or going across the yellow line cuz one day you get to hit a car head on cuz you'll make a habit of it and you can't stop you understand just had to throw that in there y'all
