We found the side tables 8 years apart and they were probably made at different times. One of them is one centimetre higher and wider than the other :). It's not noticeable, only when you put them next to each other. The tables are of very high quality. Beautiful thick black glass top, solid brass and wonderfully grained walnut veneer.
