Iwako USA will often send us pre-production samples of up and coming Japanese erasers. Sometimes we receive these months in advance of retail release. We post these Japanese erasers on the site along with an expected shipping date.
Sometimes, when we receive the Japanese erasers that will be for sale, we find the colors have changed. So far, this as happened with the planes, horses and wood furniture.
We have created a new section called "Pre-production Samples" to show these one of a kind Japanese erasers.
