Zensinsyoji is the smaller of the two companies that make Japanese erasers. Their output of cute erasers is small compared to it´s cousin, Iwako. As a result, we have been out of stock of many of their Japanese erasers.
We had stock of the Green and Orange Top Hat Penquin Pair Japanese erasers for about a week. We did not even have time to save a few for ourselves. The Square Cake Japanese Food erasers have not been available for such a long time, that it´s bin in the stock room has been given over to Iwako´s Strawberry Tart Erasers.
Scarcity can make something more desirable. Such is the case for some of the Zensinsyoji Japanese erasers.
