Summer essential: Body shaver

I bought this at Olive Young a while ago and have been using it ever since, just replacing the refills. It has a soap bar attached to the side of the blade, so it lathers automatically, allowing for gentle hair removal. I've never once gotten a cut, and it's really great. I think I've been using it for over 7 years now. I am a bit worried that the soap might dissolve in water, but it seems okay if I dry it thoroughly. Haha. It's definitely a must-have item that I use all the time in the summer.
