I honestly haven't seen this much densely-layered sexual innuendo in a good long while. Just read the box.
From what I can gather, you alleviate tension by vigorously rubbing an anime-haired Asian guy's balls all over your body. Hahaha, "ideal for use at home." I bet.

They should re-write that part to say "ideal for meeting Japanese businessmen in hotel rooms."
