The multifunctional design of the teacup is a detachable teacup with straw as the main raw material. The cup is equipped with a raised triangle knob on the top and a recessed triangle on the bottom. The two are used together. The triangle also symbolizes recycling. When the service life of this cup as a cup ends, its mission as a flowerpot begins. There are holes at the bottom of the teacup. When used as a teacup, the bottom of our lid is sealed. When used as a flowerpot, the hole design can be used as a leaking hole to ensure the normal breathing of plants, greatly prolonging the service life of the sprout teacup and reusing the product reasonably.
