G2’s are great pens but I wanted something that was made from better materials that would last longer. This uses gel ink so it’s pretty comparable as far as writing goes. I was using the F-701 stainless steel pen for years. I had to cut the gel JK refills to fit. On this one you don’t have to cut them because it’s made for those refills. I get 6 of these 2-packs on Amazon for about $11.
