Store stock Items aged over time Unused items. These are 100-yen mechanical pencils from Tombow and Zebra. The exact age is unknown, but they are at least 10 years old. This is the price for all four pencils. I have checked the clicking mechanism, but please understand that the erasers may be deteriorated or dirty. Please also note that the lead inside may be broken. They will be shipped via Yu-Packet Post.
