Love my tall planters, Cant beat the price for the set either!! Ive looked on many, many site and this was by far the cheapest for the set and Im very happy with them. Nice heavy plastic and hollowed out on the inside, assuming for the self watering part But I added weights to my so it wouldnt blow over since Im not actually using it for real plants. They look very beautiful with my 18 pine leaf topiary balls which was also purchased on Wayfair. Highly recommended!!
