The Dumbo is a handy tool that helps you to use an object without touching it with your hand. The Dumbo can be used to open a door or to push a button in an elevator, phone or at an ATM. It is made from plastic so easy to clean. You can easily attach the Dumbo with the key ring to your keys, so it is always within reach.
