Concrete is a versatile material adding a touch of modern flair to any decor, Each planter has been hand poured, sanded, and painted in small batches. Each one measures 4x4 inches- perfect for succulents, cacti, or other small houseplants. These pots are meant for the indoors and will not do well in freezing temperatures. Please keep in mind, they do not have drainage holes. Concrete may darken after watering but will return to a normal shade once dry.
