-Enable your children to use water independently as soon as they start walking and save water while having fun.
+The sink is designed with a lower and adjustable height for toddlers, eliminating the need for stools or assistance. Your child can independently and safely reach the faucet and washbasin. The pressure of the faucet is also adequate for their little hands, eliminating waste in each wash.
+A simple water filtering and circulation mechanism enables endless play with minimal waste. As long as the sink is tilted to play-mode, the same water gets circulated forever.
+Switch between play-mode and cleaning-mode with an easy action. Simply tilt the washbasin to the right to switch to hand washing. The sink directs the water to the disposal container in this mode.
+No plumbing required - use it anywhere in your home or outdoors. The sink is powered through a USB port which means you can run it with a mobile phone charger or a 5V battery. Perfect for terraces, gardens, playrooms, or any space where your child wants to play.
