These are round beads of Kyoto Opal. There are two packs of 6mm beads in the Kariasu color (ivory-like opal), two beads per pack, and one pack of 6mm beads in the green Yuzuha color, also with two beads. I purchased these from Kiwa Seisakujo, but I'm selling them because they don't match my style. They are unopened and new, but please note that they have been stored for a long time and the seal is open. If you would like to purchase them individually, they are 600 yen each, and 1000 yen for two. Please comment if you'd like me to create a dedicated listing for you.
