Purchased at a stationery store. Selling both together. Both have a 0.5mm ballpoint tip. ※ Please note that these items are being sold as "junk" due to the following defects: • Light Pink (purchased about six months ago) Shortly after purchase, the black knock part broke. As shown in photo 3, the knock part is loose. It has not been repaired, and the ink cartridge has been removed. (Please note that the black ink cartridge will not be included, as shown in photo 5.) Also, with the other colors, you can lower the knock part to write, but you need to lower it slowly without touching the other knock parts, otherwise the lowered knock part tends to retract. The cause is unknown. • Navy (purchased about three years ago) The mechanical pencil function broke early on after purchase. This has also not been repaired. The black ballpoint pen has a low ink level. This one has been used for a long time, so it shows signs of wear. (See photos 7 and 8) The grip was replaced with a new one 4-5 months ago. Shipping is planned via Yu-Packet Post Mini.
