I am OBSESSED with these! I've loved window boxes since living in Germany in the 1990s but always had a hard time finding ones to fit my deck railings.  I've done the wire holder with plastic box and they just looked blah. These look amazing! I can't wait until the grass grows tall and petunias and sweet potato vines spill over. I ended up also buying the supporting deck railing brackets because I worried about the composite balusters not being able to support such a heavy box when weighted with wet soil.
