Pros: The cool grey vase looks very sleek when paired with the odyssey dining table. Has a bit of a "concrete" look to it so it would fit very well in any kind of "urban" loft setting.
Cons: Although the description says "watertight polyresin" the vase seems very porous so I haven't been inclined to try it with real flowers. In addition, the vase stains easily so you have to make sure you don't have anything on your hands when touching them. The vase is also little wobbly so if you buy two you'll have to work a little to position them correctly if you decide to pair them together.
In Sum: Overall the grey vases look great on the odyssey dining table so if you have one, don't mind using fake flowers, and don't mind taking a little extra care when handling them, I would recommend them.
