Every man can use a razor, you can think about it! Buy an electric one, just one or two hundred dollars, which is economical and practical! I'm sure your father will like it very much Very thoughtful gift! There is also a thermos cup, where you can soak some medlar or tea at any time and keep healthy! Men also need health care!
