Virus Buster Ballpoint Pen Not for Sale Trend Micro Inc. Length: Approximately 14.5cm Diameter: Approximately 1cm (excluding the clip) From around 2001-2005 This is a promotional ballpoint pen from Trend Micro. I tested it for writing before listing it. The ink level is about half full, but it hasn't been used for a long time, so it may be streaky or not write at all. I apologize, but please prepare a replacement ink cartridge yourself. I don't know the manufacturer, but the design is similar to the old Jetstream. Please note that it will be sent in simple packaging (waterproof measures). #TrendMicroInternetSecurity #NotForSaleBallpointPen #TrendMicro #VirusBuster Type...Ballpoint pen Body Material...Plastic
