For Nuppy Racer: Super Retro Siphon-Style Ballpoint Pen

Retro Siphon Ballpoint Pen
This item was displayed on a sideboard and is unused, but due to long-term home storage, the ink does not come out.
Previously, a comment from someone who sold the same item stated that warming it with your finger would make the ink bubble up. I tried it, and surprisingly, it did rise. I learned something new.

Thank you for looking.
