Ikea Billy bookcases w/glass doors (which make the bookcases look so much nicer). As you can see, the bookcases fit a lot inside.I have TWO.. The first photo is of my actual bookcases, side by side. The second photo is so you can see what each bookcase looks like w/o all my stuff. Purchased ~6 months ago for $340 total. Yours for $100 for ONE or $180 total for BOTH. Great deal!
