The Desert Rainbow Pot is made of white ceramic that reminds us of porcelain. Each one has a rainbow painted on front in desert vibe shades of orange, rust, yellow and purpble! The top is tapered slightly smaller than the bottom. The 4.5” pot Holds a 2"-3.5" plant perfectly and would be a perfect gift for that plant lovin' friend. The 3.25” is great for windowsills!
