As so typical of Dream Zensinsyoji each time we receive Japanese erasers from them, the colors often change. With this batch of Penquin with baby Japanese erasers we did not get any new colors. We did get new color combinations. We are showing 15 different combinations on the site, but some are out of stock. Dream Zensinsyoji must of had lots of yellow baby penquins, as 3 of the 4 penquin pair Japanese erasers came with yellow babies.
