The Flower Pot is made of recycled plastic from Danish households, collected, processed, and manufactured in Denmark. The stackable, recyclable flowerpot has an organic finish and a marbled surface texture to create a natural look. It is break- and frost-safe down to -4 degrees Fahrenheit, and suitable for use indoors as well as for outdoors. There are markings for DIY drain holes in the bottom if the flowerpot is to be used outdoors. The Flower Pot is lightweight, durable and 100% liquid-tight so you avoid stains on the windowsill.
