Cute, Sturdy Shelf!

Bought to go in my home office and immediately loved it. It was very easy to assemble and took me only about twenty minutes to assemble. I added some super glue to make the corks extra stable, and it looks great in the room. Will definitely be purchasing another for the office.

This is the deal of the decade!

First, the packaging of this bookshelf is really impressive. They've added filler to ensure that there is no damage to the parts. Have you ever had to return a flat pack item because it was damaged? It's a total PAIN! So no chance of that here. The instructions are clear with plenty of words and diagrams to help you along if you need it. It goes together in no time at all and is very sturdy. All this for less than $30!?! How? I use these in the closet for shoe storage and they're beyond great.
