Review on Sakura Pigma 30061 Micron Blister Card Ink Pen Set: Black, Assorted Point Sizes - 3CT Set by Kelly Porter

I bought these online when I ran out of .1, .3 and .5 markers I was glad I could easily buy the ones I used most in the pack without the extra shapes and sizes to have to buy . However, these markers began to die out very quickly, say within 3-4 months, without overuse. When I first became acquainted with Sakura pens, I found a large pack of different shapes and sizes at my local art store. for a very long time before admitting that I needed the knowing. I love sakura pens, love these sizes but the ones I got are not what I expected when they started dying so fast.
