Ikea Billy Bookshelf - Customized

I have a customized bookshelf up for sale here in the building. It's whitish/greyish colour with a geometric backing on the shelves and two frosted doors. On the back of one of the shelves you will notice a cutout for a light switch (see last photo). If you're putting books on it though, they will hide it (I had a smart light switch hooked up behind it). Dimensions: 31.75"W x 11"D x 79.5"H.
