These 4 - pack green preserved moss square planter boxes are great for adding a touch of nature to your space. For use, simply arrange your favorite flowers or decorative items in the planters. If you're using them outdoors, you can poke holes in the plastic liner at the bottom for proper water drainage. To keep the moss looking fresh, avoid direct sunlight for long periods as it can cause the moss to dry out. The inner lining is removable, so you can clean it regularly. When not in use, store the planters in a cool and dry place.
