This is a listing for a total of 5 pens: two dual-color (red/black) pens and one tri-color (red/blue/black) pen. I have tested them and confirmed that they write. Some of them have company names printed on them, so please refrain from purchasing if this is a concern. Shipping will be via Rakuraku Mercari Mail in an A4 envelope. #ballpointpen Thank you for looking.
