The Parker Ingenuity is a luxury writing instrument that achieves a smooth writing experience thanks to its 5TH technology. - Brand: Parker - Model Name: Ingenuity - Features: Uses unique 5TH technology - Purpose: Luxury writing instrument - Condition: Unused Thank you for viewing. This is a fountain pen I bought for myself at Haneda Airport in 2019, but I ended up never using it and it has been stored away. It is unused. Therefore, ink has never been run through it. Consequently, I am unsure if the included ink is still usable. Please understand this before considering a purchase.
