When I bought my bookshelf, I also found a cute cupboard that I thought would work perfect for my makeup. My bathroom is small and my makeup has taken over the counter. It was hard to find anything and I needed more room.
It was a little more difficult than the bookshelf to put together, but I managed just fine. It does mount to the wall, but about the only place to put it would've blocked my only electrical socket. But it fits perfectly on the counter.
I love how organized my makeup is now! Everything is is so much easier to find.
