We can tell by the analytics on the site, that almost all the interest is centered on the Japanese erasers. (Analytics, for those who do not know, is a way for us to see what you are looking at on sausalitoferry.com). We agree with you that the Iwako and Dream/Zensinsyoji Japanese erasers are worth all the attention.
In the section 1 to 40 Erasers there are erasers that are distant cousins to their Japanese eraser counterparts. The pandas in the box are such erasers.
They do rate pretty high cutness factor, but they will always play second fiddle to both Iwako and Dream/Zensinsyoji Japanese erasers.
