Made in 1990. This is a set of 12 pencils featuring Sanrio's character "Kero Kero Keroppi," with 6 pencils of each color/design. They are already discontinued and I think it's difficult to find them in stores. These are individual pencils for sale. They were stored in a transparent case with other pencils. Perhaps due to poor storage conditions, there may be some discoloration, stains, and uneven coloring. Also, since they are old, there may be damage that is not visible from the outside. To avoid any problems, I recommend that those who are even slightly concerned about the condition refrain from purchasing. No bulk discounts will be offered. Even if you purchase multiple items, please complete the payment process for each item individually.
