Pro_Shop Polar Pen ink refill 4 Packs Black Color

Extremely satisfied with these. It's so challenging to find a proper replacement cartridge (let alone four) for the Polar Pen.The last time I bought from a different seller I was mislead about quantity and had to modify it to fit, also it wrote poorly..These fit my pen beautifully, and the tip writes quite smoothly! If you're a Polar Pen owner and need more refills, this is a great choice!

I wish I could leave zero star review. Overpriced refills last a day and then dry up. Complete waste of money. Terrible, terrible product. Useless.

works well
