Please carefully review the product description and photos before purchasing, and make your purchase only if you are satisfied. ○Product Details○ Product Name...Knock-type Handy Handy Pen Touch Artline Artline Mackee Knock Manufacturer...Pentel Pentel SAKURA SAKURA ZEBRA ZEBRA Shachihata Shachihata Colors...Red, Blue, Black This is a set of oil-based markers and cartridges. Handy and Mackee Knock are knock-type markers. ○Reason for Listing○ These items were included when I previously purchased a large quantity of writing instruments for collection purposes, but I am listing them because I have no plans to use them. ○Condition of the Product○ One of the blue Mackee Knock pens did not have ink. I confirmed that the others have ink. They were in their packaging until I tested them, so I believe they are almost new and unused, but the remaining ink level is unknown. Please judge the detailed condition from the photos. ○Other Notices○ The product condition is based on my subjective judgment, so if you have any questions, please ask in the comments before purchasing.
