I purchased the POSCA...

I purchased the POSCA in an attempt to find my holy grail- a white brush pen.
Unfortunately, the POSCA has a lot of issues that prevent it from being such.
1. The ink is watery, and will reactivate non-water-safe ink if applied on top
(very important if you're a comic artist, and are using the white brushpen to
make corrections) 2. The ink isn't fully opaque, so even if it does not
reactivate the ink beneath it, there will be some ghosting 3. The pen is
pressurized, and may leak during barometric pressure shifts (or in an airplane
cabin). Unfortunately, I do not reccommend this product.
