Cardboard cup sleeves aren’t as effective on cold cups as insulated cup sleeves
If cardboard sleeves absorb moisture, they become soggy. They don’t hold in cold temperatures. Kup Kollars are insulated with Thinsulate insulation by 3M which is used in ice coolers. They slow down ice melting so your drinks don’t taste watery. Frosty drinks stay frozen, longer. Your hands stay dry because Kup Kollars absorb the condensation on cold cups.
Would you rather keep your cold drinks in a cardboard cooler or a Thinsulate insulated one? Kup Kollars are miniature ice coolers you can put in your pocket or purse after your frosty beverage becomes a fond memory!
