This is a set of a CROSS ballpoint pen and a leather case. It was a gift, but I am selling it because I don't use it. I believe the ballpoint pen is a Wonderlust Malta. - Brand: CROSS - Color: Silver - Accessories: Leather case - Type: Ballpoint pen Basically, it is a new, unused item, but I did test it out. Also, although it is not noticeable, there is a slight stain on the outer box. I think the ballpoint pen is a thick type, but I don't know the exact millimeter size. This is a perfect item for gifts, etc. Thank you for looking.
