Japan cm of the week - a boob window

This cute little commercial from Heiwa has been on the air for a while but I've seen it a lot on TV this week so decided to post in now.

I like this commercial for three reasons. First, the changing picture frame is a pretty cool idea. Second of course is that the commercial stars Sayaka Ayama (佐山彩香)and Arisa (亜里沙), calendar girl type models that you don't see too many of in commercials in Japan.

Oh and the last reason is the cm itself doesn't make any sense. What the hell are they even selling here? I guess you can check the Heiwa page and find out.
