I love the bean! The smaller sizes do not seem to have her name stamped on the back. I have the 12mm and I love it! I had the 9mm, but it was a bit small for me, I am 5' 5" and of average weight, so I exchged it for the 12. I think that if I were more petite the 9mm would have looked better.
Go for the bean! Or the floating heart. Don't bother buying the polishing cloths, you can get one for cheap and it will do the same exact thing if you buy it from Walmart or Tiffanys. The only difference will be price.
Is it stamped on the 12mm?
