I found one key holder that matches my needs. As the keys can be swung into the inside of the leather strip, it can carry keys neatly and the size of the entire key holder would be smaller than the conventional ones. Thus, I can easily put it into my pocket. Nevertheless, the key holder has opened sides, so there is still chances that cause damages of the pants’ lining. I need to make a lock to hold keys in a holder.
