Doorknob Silicone Sleeve / product

Doorknob Silicone Sleeve

In the winter,the weather is so cold and dry that static electricity is easy to be generated when human body touch the metal.We go to touch the doorknob to open the door when there is always static electricity.If the doorknob put on these insulated doorknob silicone sleeves,people will be no longer worried about static electricity.
The doorknob silicone sleeves have three sizes, there are large, medium and small.They are used to cover different sizes of spherical doorknobs,respectively.And they are made of resilient silicone materials.This will not only protect the human body from electrostatic damage,but also decorate the doorknobs.
