This is a product from Kotori. It has a cute little heart pattern (*^^*) It can be used for both hot and cold items. Not only for baby bottles, but also for baby food, drinks, snacks, and lunches, so you can use it not just during infancy, but for a long time! Brand new, unopened. Since it is an unopened item, we cannot be held responsible for initial defects. We are also selling a pack holder with the same design. We will ship it by post, so it may be flattened. If you are concerned about deformation, we can ship it in a box for an additional ¥250. Please comment before purchasing (*^^*)
