This is a set of 15 whiteboard markers. They are unused and have been stored at home for several years. I checked to make sure the ink comes out, and confirmed that all of them work. However, the green marker's color seems a bit faded, so I'm offering it at a lower price. Thank you. *Please refrain from price negotiations. *I do not need any Mercari-specific, troublesome, original rules other than the official rules. - Colors: Red, Blue, Green, Black - Type: Whiteboard markers - Features: Water-based ink - Quantity: 15 (Black x 3, Red x 4, Blue x 4, Green x 4)
