I saw this online before I went to Japan. Then during the final days of our stay I was reminded of it and went straight into the store. Luckily they had it in stock.
They also had matching earrings, I will post them later... ^^
It's one size, and lucky me to have quite small fingers. I prefer the big ring with the flower, but I will probably use the set. I chose silver because I recently bought a ring in rose gold.
You can purchase them here
