We usually use electric plugs without awaring whether it is comfortable or not.
For children and old people, sometimes pulling out a plug is really hard so they use both hands and struggle to pull out. Most of plugs are remained as it is get inserted because of the trouble of pulling out the plug.
We suggest a brand new type of plug which has an one-touch button. We can pull out the plug very easily with use the ball pen mechanism. This behavior gives fun and prevents wasting of energy.
