The G1 Parker ballpoint pen refill is a classic international standard refill widely used in business pens and office stationery. Measuring 98mm in length and about 2.5mm in diameter, it is designed for smooth, consistent ink flow, making it ideal for daily writing, signatures, and professional use.
This type of refill is commonly found in Parker-style pens, luxury ballpoint pens, and metal signature pens, offering both reliability and long-lasting performance. Many buyers often confuse G1 with G2 refills — while G1 refills are shorter and slimmer, G2 refills are slightly longer (usually 100mm) and thicker, so it’s important to check your pen’s compatibility.

The G1 Parker ballpoint pen refill and the G2 refill are both popular standards, but they are not the same size:
G1 Refill – A slim, shorter refill measuring about 98mm in length and 2.5mm in diameter. Commonly used in Parker Jotter, Lamy BP, and many slim metal ballpoint pens.
G2 Refill – A thicker, longer refill measuring around 107mm in length and 6mm in diameter. Known as the “Parker-style” standard for most modern ballpoint pens.
Compatibility Check – Always confirm your pen barrel before ordering. A G1 refill will not fit a G2-compatible pen, and vice versa.
For businesses purchasing in bulk, making the right choice between G1 Parker ballpoint pen refills and G2 refills ensures proper fit and smooth writing performance without returns or mismatches.
