I got these after a bad experience with red Sarasa pens (otherwise a GREAT brand, with wonderful pens). For whatever reason, the Sarasa red pens died out long before the ink was used up, and didn't make solid lines after they had been used a bit and stored for long periods (who uses red pens more than occasionally and for more than for short periods?). Anyway, these Bazic GX-8 oil-gel pens have solved the problem. They write quite clearly, and seem to have no problem with being used a bit from time to time, while spending most of their life in a drawer. I haven't yet had any of these pens fail to deliver a consistent line of ink, or had to scribble with them to get the ink spreading correctly. They make a narrower line than I'd consider ideal, but it's quite legible, and is likely the same as most ballpoint pens (I'm spoiled with the bolder gel ink from the blue and black Sarasa pens). I don't know what difference the "Oil-Gel" makes, but I'm suspicious it is why these pens haven't had any issues with drying out or delivering spotty lines after spending most of their time gathering dust.
