plant coaster / articles for daily use

In office life, the cups and cold drinks we drink often drop water on the surface of the cup or can, which will stain the surface of the desk. The plant coaster is made of degradable straw, which is a kind of degradable material. The cup mat has strong water absorption, and can store the moisture, and keep the environment inside the cup mat moist. Plant seeds are sown in the inner materials of the cup mat, and the seeds can absorb water and grow gradually. After the seeds grow and germinate, they can be transplanted into flowerpots, and the coasters will gradually degrade to provide nutrients for plants.
