This is a pen set containing two mechanical pencils and one ballpoint pen. I was told it was distributed when a family member was employed, but I don't have any further details. The ballpoint pen is likely wooden, and I confirmed that the two mechanical pencils are plastic and the lead comes out when clicked. The eraser on the cap shows some signs of use.
