These are dragonfly beads with ears, like Totoro. Approximately 3.5cm tall. Set of 7. It seems my family received these as souvenirs and had them displayed in a cabinet. You can slip thin memo paper or similar items between the ears. They look beautiful when placed near a window or in a place where light shines through. There are no noticeable scratches or stains, but please refrain from purchasing if you are overly concerned, as they have been stored at home.
