Epson ELPPN04 Interactive Pen Set with Case

Got these Epson interactive pens from a BrightLink projector setup. They're the ELPPN04 models, one with the blue tip and one with the orange tip so two people can write at once. They've been used but still look decent and come in the original hard plastic storage case. Good if you lost yours or just need some spares for the classroom or office. No batteries included but they just take standard AAs.
