Please read the profile. This is a set of 8 ballpoint pens from a pharmaceutical company and an airline. In the bag: pens from the pharmaceutical company. Red/black, two-color: 1 pen Black, single color: 3 pens The other 4 pens are black, single-color pens from the airline. Since they weren't in a bag, 3 of them have been tested (about 2cm of writing). The remaining pen has a cap directly on the tip. I don't think there are any particular issues, but please refrain from purchasing if you are concerned.
