Fountain pens are the ultimate in no-waste - Clean them, refill them and keep using them. I have a handful, the oldest is 73 years old, but I have several that are around 50 years old. Cleaning, refilling with ink, and very rarely, a new nib (quality fountain pens have nibs coated with very hard metals that last for decades) keeps them going indefintely. Quality is worth the cost here, but by the late 1920s we knew how to build quality fountain pens that do not leak and definitely last!
