This is the Mitsubishi Pencil multi-function pen, the Jetstream 4&1. The ballpoint pens are black, red, blue, and green, with a 0.5mm ballpoint diameter. The mechanical pencil is also 0.5mm. The barrel color is white from the limited edition Monotone Collection. Normally, this color is available with a 0.7mm ballpoint diameter, but this one is 0.5mm. Although it is new and unused, it was a store display item. There is no box. If you wish to have it delivered to a post office or convenience store, I will change the shipping method, so please comment in the comment section before purchasing. uni jetstream 4&1 special color white discontinued out of production
