Wow!
Color: Farmhouse White, Number of Items: 2
This comes as a two pack and I was thinking it might be cheap looking or be made of inferior materials. These end tables are solid and beautiful when put together. They come unassembled but the instructions are very clear and understandable. Highly recommend this product. Well worth the price.

Well engineered!
Color: Farmhouse White, Number of Items: 2
These are really quit easy to assemble. They're well engineered. One or two extra screws/parts in case you loose one.
When they're done, they look Very Nice! I have tremors and was still able to put them together, it took alittle longer that an hour, but still not difficult.
