Tokyo Disney Resort 2012 CHRISTMAS WISHES This is a mirror keyholder purchased at DisneySea. I believe you could customize it with initials. The diameter of the mirror is about 3cm. I've included photos 6 and 7 of the original bag from the purchase, but it's severely deteriorated. I can include it if you'd like, otherwise, please let me know if you don't need it. I will wrap it in bubble wrap for shipping.
