About this Product
Take your ears anywhere you want to go in time and space!
These are a bit DIY in the sense that Shapeways doesn't currently include earring hooks on this specific model. That is why they are much cheaper than the earrings that do include the hooks. I don't know when that will change, but for now you will have to put on your own hooks. Sorry about that.
