solid item, worth it.
Size: 9 Cube Shelf
solid wood, well designed and easy to put together. A few of the back pieces were bowed but thats what you get with wood and it all went together just fine, can't even tell. They are unfinished, but ready for stain or poly Its not often I am pleased with furniture off of Amazon but I will be ordering a few more of these.

Safe, Simple, Reliable!!
These adapters are heavy‑duty and dependable. The fireproof build feels secure, and the grounding tab adds peace of mind. Perfect for older outlets, they fit snugly and keep devices running without hassle. A practical, no‑nonsense solution that delivers safety and convenience in bulk. I have converted most of my outlets with this.
