This clever, reversible design means that you can drain the washing up virtually anywhere & is perfect for creating additional draining space when required. Both sides of the board have sloping ribs that prevent water being trapped in the mouths of upturned cups & bowls. On one side an integrated spout allows water to be drained directly into the sink, but when the board is flipped the design captures the excess water, trapping it at the opposite end for draining later. Non-slip feet on both sides keep the unit firmly in place on the work surface.
