Popular items from the official "LINE FRIENDS" shop. This is a cute cooler bag with a BT21 design and summery pastel colors. This bag can keep items warm or cold, and can easily fit a 500ml plastic bottle laid on its side. It's a large size, so it can easily hold a lunch box and drinks. This is a sold-out item, so you can't get this cute design anymore. The opened one is the one I use, so it's for reference.
