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
