Why is it that when the typical ball point pen sold in USA runs out of ink I have to replace the entire thing: the body, the ink tube, the tip, the clicker, and the 2 springs?
Yet, when my pretty unremarkable Japanese ball-point pen runs out I just grab a replacement ink tube & tip?
When my lowbrow Lamy Safari fountain pen runs out I just replace the ink cartridge?
Why is pen stuff so needlessly wasteful?
