A paper "cup sleeve" that makes it easy to hold a cup of hot drink. After using it, it's usually thrown away with the cup, so it's a waste.
The new product "Paper Cup Sleeve" from the 100-yen shop "Daiso" is a polyurethane sleeve that can be used repeatedly. It has a luxurious leather-like texture, and a non-slip material is used on the inside.
There are two sizes, large and small, and the corresponding cup sizes are 360 to 520 ml for large and 205 to 270 ml for small. By the way, the large size was perfect for the tall size of Starbucks coffee.
The sleeve also has a strap hole, so if you carry it through a ball chain etc., you can take it out without hassle. Why don't you carry one fashionable sleeve that can be used as a landmark for your drink in the office? The price is, of course, 100 yen (excluding tax).
