Not for sale. This is an original Hiyoko-chan (Chicken Ramen's mascot) insulated lunch bag. I love Hiyoko-chan and collected this one. I opened it once for the photos, but it's unused. It's a triangular shape that closes with a snap. Please refer to images 8, 9, and 10 for the size. It's about the size of an open palm on one side. I think it's suitable for children or those with small appetites. It also seems good as a small bag for walks. Thank you.
