These are super cute! I would totally order these for my wedding when I get married! They run from $50-$350 depending on the design. I've included some of my favourites here. You can check out their other designs at Kikuike.
Kikuike is composed of 3 professional sculptors who I believe use some sort of lightweight clay to create these toppers so that they won't weigh the cake down.
Showcasing some kawaii illustrations by the talented Jerrod Maruyama! I found out about him back in March and have been admiring his work ever since! Check out his flickr and his online store!
I love his work so much that I've used some of his images, with his permission, to create my jewelry. ^___^
