A cone for constant watering that you just attach to an empty coke bottle. This item was developed in Japan with the idea of using some of our discarded, empty bottles of Coke, etc.
The Japanese manufacturer felt that it would be so very helpful to the environment if we could use some of our daily castoffs as a water reservoir and just attach his extremely useful product to it. These plastic spray nozzles are designed help you along with the care of your Bonsai ....and for that matter.... the care of all your plants.
This item is a slow release watering cone. It is 3 1/2" long and has one small watering hole close to the tip for drip type watering. This can be used as a slow release watering unit for fertilizers.
