I couldn't help but notice that you are in Japan. I live in Yokosuka (just south of Tokyo).
I've been wanting to try those foot detox pads. I went into a pharmacy one day and looked around but didn't know where to find them.
Can you describe what section I might find them in at the pharmacy and what the box may look like? I really don't know enough Japanese to ask for them. Do you know what they are called in Japanese so I can ask? I have a few Japanese friends, but as we are all mothers of small children, we don't really have time to go shopping at the pharmacy together.
