Except dressing up with those cool steampunk leather masks at costume party, I really don’t have any good idea to correctly use it. I believe I would never use it as a SM tool.
However, Bob Basset give the cool gadget a new life. His steampunk leather mask is not only a mask, but also a speaker. You can imagine how bright you will be when you listen to MP3 with the steampunk leather mask integrated built in speaker. Moreover, you might find the speaker just like a “trumpetflower” in the retro phonograph.
