I am selling everything I have on hand, so I ship the same day at the earliest! I do not offer discounts, so please purchase as is! I have multiple stocks, so if you contact me via comment or after purchase, I will prepare a separate listing page. This is a "G2" standard refill. It can be used as a replacement core/refill/Refill for Parker PARKER pens. This is a set of 5. Although not a genuine PARKER product, it is a high-quality compatible product with a writing feel similar to the genuine product. It is as smooth and comfortable to write with as the genuine product. For those who prioritize cost performance. Because it is a "G2" standard, replacement cores made to the same standard have the same shape and dimensions, so they are compatible with any manufacturer, just like mechanical pencil leads. It is used by many overseas brands other than Parker and has a lot of compatibility. Color: Black (oil-based) Character size: M (medium) Body size: Total length approx. 100mm Tip: Ballpoint pen
