I bought this, though it wasn't cheap, but it was so cute that I ended up keeping it at home and never using it. It's not made of rubber, but it has a slight stretch, so I think it's around a size 10-11. It's a large, well-made, and beautifully three-dimensional heart, so I think it's quite rare. The plump heart that sits on your finger is cute and has a strong presence, making it very adorable. There is no case. I will wrap it in bubble wrap for shipping. I am also selling different colors and sizes. Cosplay Point Ring Heart Ring
