Minimized size - the external size reduced to eight mm. It is slim enough that the furniture close to the wall is not interfered. What’s more, the minimized plug can also be plugged into multi-socket outlets without interfering with the neighbor outlets. Easy pulling-out. We innovatively used a slim, soft material sheet at the plug. The slim sheet is so elastic that it can be pulled out with the fingers easily, and get back to the original state while your fingers are released. No labor assembling cost is needed since it only requires injection. The use of less material as well as a shorter production time contribute to environmental protection.
