Purchased on a JAL flight about 8 years ago. Adorable motif muse. Use with the lid slightly ajar. Diameter 5 cm, thickness 2-3 cm. Comes with a dedicated pouch, box, and instruction manual. It has an alarm function, so I used it as a travel companion. It has a feminine and cute shape, and is compact and convenient to carry. Please note that there are signs of wear. Please replace the battery before use.
