Spill-proof basin / basin

When we walking with one basin of water at hand,the water may spill out easily,especially when the water is quite full.And also when we wash our clothes by pressing it within the basin,the water may overflow and get floors wet.This design adds a silicone circle to the original basin,and it can be turned up when we need it,so that the swaying water will be stopped from spilling out.It also offers some room for the swaying water when we press our clothes, and the water will not overflow based on this.
