Thank you for your interest. This was found in the storage room at my parents' house. It's a stock of supplies. One of the two knock-type refill leads has been taken out of the cardboard backing, but is unused. Chaco Liner Pen Type: 1 Cartridges: 2 Knock-Type Chaco Pel: 1 Chaco Pel Refill Leads: 2 Refill Lead Sharpener: 1 My mother used white Chaco Liner, so I think the blue ones have accumulated. The pen and sharpener have been used. Please feel free to use them if you'd like. #CloverChacoLinerMadeInJapan #CloverChacoPelRefillLeadsMadeInJapan
