There are still many Japanese eBay retailers who have this art book available. Just search "Monogatari Series 10th Anniversary Artbook" and set the location to worldwide.Long shot, but looking for Monogatari Series 10th Anniversary Artbook
It was just released in January this year and already went OOP. Damn it, I would have preordered it back then, but somehow thought this was just going to be a DVD with the illustrations instead of actually being an printware artbook...
Actually I was nore hoping somebody here may want to sell it, or know somebody or so. Have seen the ebay sellers, but they are more on the expensive side and more than Japan isn't shipping anything with SAL atm, so shipping would probably cost around as much as the original listing price for the book.There are still many Japanese eBay retailers who have this art book available.

I hope this information helps you find what you're looking for.
I'm selling one of those! £35 plus P&P, it's opened and I watched Season 1 once but it's in very good condition, could probably be considered like new. Let me know if you're interestedSnow White with the Red Hair Seasons 1 & 2 (Collector’s Edition Blu-ray) Anime Ltd.
