Unused click-type ballpoint pens, one JETSTREAM red and one blue, and four refills of each color. The model number for the pen body is SXN-150-10, and the refill is SXR-10. The ink thickness is 1.0mm, which I think is easy to use for things like circling answers. The list price is 150 yen for the pen body and 100 yen for the refills, so how about this great deal? All items are unused, but please understand that they have been stored at home.
