Iungo Compatible Parker Gel Ink Ballpoint Pen Refills for Parker Jetstream Prime (Blue-Black, Plastic, 10, 05)

✒ We have started using Parker-type gel ink in metal pens. The dimensions have been improved to make it even more compatible than the resin version. The standard was developed by the British brand Parker, so it's also called the "Parker type." The G2 type refill is used by many international brands, and is the most compatible standard for large-capacity refills. ✒ [One sample will be sent free of charge] You can test the writing comfort and see if it fits your ballpoint pen.
