This is a beautiful jewelry box! I, personally do not own this piece itself, but I've seen it in detail at the NYC
F.A.O Schwartz store. They have a large
Noble Collection display with some of the Narnia pieces, including the Wardrobe Jewelry Box. The details on the outside of the box, and on the door closely resemble the original ones of the wardrobe in the film. The carvings are very nicely done and each one is obviously symbolic to the storyline of the
Magician's Nephew! The inside of the wardrobe has some shelves for placing your jewelry and is lined with a burgundy soft coating all throughout. The top of the wardrobe pulls up as well to reveal another storing compartment. You've no doubt seen the pictures of it, but I'm just giving you my thoughts on how it looks in person.
It's pretty much expensive wherever you can find it, especially on the 'official' sites that sell it, so EBay is most certainly your best bet!
I hope you find it! Good luck! It's really a lovely piece to have in your collection!
