Anti-gravity air grass

//Test tube size: 4.5cm diameter x 15cm height // Airweed is extremely adaptable, and it does not need special maintenance when placed in a test tube. It can survive as long as it avoids violent sunlight, high temperature, excessive humidity or arid environment. *The airweed needs to be taken out from time to time to add water slightly. *Because of the subtle activities of the plants, the airweed has the opportunity to try to grow in accordance with the shape of the test tube, which will reduce the force between the test tube and slowly downward. At this time, you need to put the air grass in another direction. *Please note that this is a plant work, which can only be shipped within Hong Kong. *The secure packaging box ensures that the work is delivered to you safely. *The test tube is a fragile product made of glass. *Please be careful to protect children and small animals from putting the works in your mouth.
