I have black iron furniture, my coffee table, end table and long behind sofa table, and the vases with the black iron base is perfect. The size of the glass bulbs are perfect in overall view of the piece, adds a delicate substance which I appreciate. I have not put flowers in them yet or I would attach a photo. If possible I would love to send you a picture in a few days as it would show your viewers the completed look. Send me an email if this is possible.
Thank you for your store, I just love Wayfair as it has become my one-stop shopping site.
