Made in 1990. This is a set of two packs, each containing two erasers with different illustrations. I photographed them still in their packaging, so the designs may be difficult to see due to light reflection. Please refer to the ruler in the photo for size reference. The thickness is approximately 0.8cm. From a quick inspection, there doesn't appear to be any significant damage, but the contents are unknown as they are unopened. Being old items, there may be damage that is not visible from the outside. To avoid any issues, I recommend that those who are at all concerned about the condition refrain from purchasing.
