Purchased as spares for pens and stamps. I don't use them very often. One pen and three stamps. No main unit. The edge of the extension line above Baikinman's right eye is slightly chipped, but it was like that when I bought it. I don't think it affects the stamping. The pen has a triangular shaft. There is no main unit, box, packaging, or instruction manual. *Everything in the photos is included. To reiterate, "there is no main unit," so please be aware. Character names: Anpanman, Dokin-chan, Baikinman
