In china,you can't plug a two-pronged plug in the three-hole socket.
Now we come up with an idea to make it possible.
Rubber is a good insulator , and it has plasticity.
So we made a few changes in the traditional two-pronged plug.
We changed its shape into a "U" by rubber, So you can bend it,and orange bar will prompt you the extent of bending deflection , so that you can plug it in the three-hole socket with right angle.
You will find it’s very useful in some cases.
