The Premec Jumbo Gel refill is a Swiss-made Parker-style G2 refill. It uses a vibrant, but watery ink that is slow to dry but looks excellent on paper. The pen has a very short writing distance — just 400 meters for the 0.7 mm version — but has many admirable qualities which Premec makes clear on its packaging. The ink is smooth and fun to use, but prone to smearing on any paper with any degree of ink resistance (like a Rhodia).
Premec’s gel ink conforms to EN-71 and ASTM D-4236 regulations, meaning is if free of heavy metals, it’s light-resistant to ISO-27668-1 standard, and it’s corrosion-resistant.
The tip of the refill is 2.5 mm, which makes it too wide for some pens, like the Rotring 800 ballpoint.
The refill uses a polypropylene body, stainless steel tip, and a carbine ball.
