I bought this especially for my little sister, so it's wonderful that it has both practical and pretty applications!

I've yet to show her Card Captor Sakura, so the Egg Motif was the way to go - in addition to being a more complete representation of the in-universe object. Owing to its plush nature, you can fit a good number of appropriate items in the pass slot (like stickers!) or in the wonderful inclusion that is the coin-purse.

It may not be as durable as a full fledged wallet, but it does exactly what it's supposed to (and a little more) and looks lovely doing it.
