Alexander Background Books - find-able, and try-on-able in the wardrobe... not find-able on site?

That item belongs to an NPC avatar! It's not available to users. c:

There might be a few similar items that are available to users if you need it for a HA. The Abalone Bookmark comes to mind.

It's probably a bug that you're able to find them in the wardrobe but I'm assuming it's the background books for [NPC] Alexander's HA

Thanks guys~!

The new wardrobe shows NPC items. So you can try on Titania McGee's shirt :P
