Seesaw Cover / drain cover (Products)

Seesaw Cover
Seesaw Cover

Seesaw cove is the cover design for the drain, helping water to flow and preventing stink from the drain in the sink at the same time. This design is based on ‘the principle of a scale’, opening a cover, when water flows down and it becomes heavy, and covering the drain, through the balance of right and left, when water doesn’t flow. In addition, if it is separated from the sink with its handle,users could easily take out of food waste. As this design doesn't require any special machines, it is really easy to install and economical.
