Pichu and Celebi ballpoint pen set from Pokémon. - Brand: Pokémon - Colors: Green, Transparent - Colors: Blue, Transparent - Characters: Pichu and Celebi I believe the ink has deteriorated over time. Please consider this for collection purposes. The pens are dirty from being stored. The green Pichu pen has very little ink left, and the Celebi pen has about half left. I tried using them after a long time, but the ink didn't come out. The pens are covered in dirt. Thank you for looking.
