This is a set of 18 ballpoint pens. Some pens combine a highlighter and a ballpoint pen. There is also one tri-color ballpoint pen. Most of them have the names of pharmaceutical companies printed on them. There are also some ballpoint pens without the names of pharmaceutical companies, so please check the photos. I have a lot of them, but I don't use them, so I'm selling them. They are unused, and I haven't tested them, so I don't know if the ink will flow properly. Please only proceed with the purchase if you understand this. Please refrain from purchasing if you are looking for a perfect item, are prone to making unreasonable claims, or are overly concerned about minor details, as I am a private seller and may overlook something during inspection. I have a cat. I store the items in a place where the cat cannot enter, and I take great care to prevent cat hair from getting into the packaging, but please be aware of this if you have allergies.
