This is a set of 10 mechanical pencils. Please check the photos for the manufacturer and type. Some have been used, so there are minor scratches and signs of use. All lead inside will be removed before shipping. (※Lead is not included) I have checked that they work, but there may be oversights due to my amateur inspection. Please purchase only if you understand that these are used items. Feel free to comment if you have any questions! Instant purchase is welcome!
