Popular mug from KEYUCA I've been using it for about a month, but I've cleaned the inside thoroughly. It keeps coffee from getting cold easily. A stainless steel mug with a rounded shape and gentle colors. This popular mug can be used for various purposes and keeps drinks cold or hot. Large size with a suitable capacity of 320ml 1. As a mug, by directly pouring beverages into it 2. As a cup holder, for takeout drinks from convenience stores or cafes, with the cup inside 3. As a holder for 300ml bottles or cans For those who understand that this is a used item, thank you.
