Perfect
Color: White, Number of Items: 2
These are the perfect size. A little long cumbersome putting them together. They look very nice for a small nightstand

Was easy to put together, and it's sturdy. It didn't come with any white dots to cover screw holes, so I ordered as some on my own.

GOOD BUY
Color: Grey, Number of Items: 1
This is a good sturdy table. It is the perfect size for an end table or nightstand. The USB ports and Outlets really come in handy. It is made out of real wood which is rare, it is definitely worth money.
