As always, Wayfair never disappoints, I love this set, it is battery operated and has built in timer, the directions in the box were for the electric set but no biggie for us, I knew it was battery operated. They fit perfectly around our electric fireplace. We live in a mobile so space is always a thing as well as having pets. The trees are already attached to containers, unfold the garland. Batteries not included.   I love Wayfair my number one place to shop always! Highly recommend this product!
