Plant markers!! No more confusion or mistaken identity of your plants. The plant markers are made from high impact recycled styrene. They have a smooth writing surface so that you can use a pencil or sharpie marker. Just soak the plant label in alcohol to clean off the sharpie! These plant labels make it easy to keep track of where and when your seeds were planted, the variety and other important information. Use these for indoor or outdoor growing projects. Also listed are the 5" inch plastic plant label. Photo shows the 4" and 5" plant labels.
