This is one black F replacement ink cartridge for a Caran d'Ache pen. I purchased a new Caran d'Ache 849 and only used this cartridge for a test write, as I intended to replace the refill with a different brand from the start. The case is not included. I will package and ship the cartridge. No price reduction is possible. - Brand: Caran d'Ache - Model Name: Ballpoint Pen Refill - Color: Black - Size: F Thank you for looking.
