I have a kh 4444 laser pointer pen and I want to refil the pen. The current cartridge is 1.7mm thick all the way through, is 6cm 6.5mm long and is made of metal. The funny thing is, the nib is the same width as the rest of the cartridge so its extremely hard to find a pen cartridge like that. It's also thinner than any other cartridge that I have ever seen.
Please help me find a refil
Thanks - AML(AnswerMeLater)
