I initially bought my first set of these pens (.7mm) when on vacation in Japan. I absolutely love them. The only drawback I have found is the ink runs out too quickly. I am absolutely ecstatic to have found an online store where I can purchase refills.

I also found that if you leave the pen in your car on a hot day or it is exposed to heat the ink will not work. You can solve this problem by putting the pen in the freezer (below 14 degrees F) and the ink will start working again. The ink is heat sensitive. Hope this helps everyone!
