I have this in the polka-dot case. It writes very smoothly but sometimes it does skip. I think the UM-151s write more smoothly, but the UM-138s are so much more comfortable to write with for extended periods of time. The UM-138s also have a bit more friction when writing than the UM-151s, which I like because it helps me control my writing a bit better. Overall, this is a really good pen.

I love these pens. This color is one of my favorites. The lighter blue is kind of too light and matches the lines to my college ruled notebook paper. This one is moderately bright and very legible.
