nice LITTLE tables
Color: Black, Item Package Quantity: 2, Color: Black, Item Package Quantity: 2
these tables are ..... easy to assemble sturdy nice to look at HOWEVER missing 2 stars for... they are small and plugging in items such as my laptop cord made it bulky and always in my way. if there was a middle shelf that would help with the small tops if the outlet bar was on the side or under the top that would help with the bulky cord issue
