From South Korea.
I’ve bought an extra cartridge to use on leather. I did not use it a yet. So I can’t tell you anything about the quality. It was easy to switch the cartridge. It wasn’t clear to me that I Could switch them when they weren’t finished yet. So when asking you, you responded quickly and accurate. Maybe you can add this in the instructions. And maybe advise to keep the cover to store It seperately from your pen. I’ve thrown It away, unfortunately. You told me It was better to store It seperately.
reasonable and timely thanks great for paper work
