Definitely need a drill for this installation! I LOVE these shelves! They make my living room so much more classy and cute! It also makes a great room divider since all sides are polished and pretty! It is small enough to go in most any space but large enough to hold a lot of items to display. The solid sections allow you to tuck away things too! I keep getting compliments on this piece. I am super happy with it. The only complaint is the screws should be painted white to blend in. They gave stickers to cover up but they don't stick.
