DescriptionSpecifications
With their Signo RT1 pen, Uni-ball unveils an innovative tip design. The tip is rounded and edgeless to reduce friction against the paper, resulting in a super-smooth writing experience. Mirroring that smoothness is the simple body consisting of a clicker with clip, and a rubber grip that blends almost seamlessly into the barrel.

This sleek pen puts down a consistently smooth, very fine dark line. No smudges, no blotches. Simple design. Very comfortable to hold when writing.

Writing another review because... why not? I love these so much that the two I bought never left my pocket until there was absolutely nothing left in the ink cartridge. Best $2.50 I've spent in my entire life!

It is reluctant to start laying down a line, and has very inconsistent ink flow. But, I've filled two A5 pages of good paper and some lines almost no ink gets laid down. Even when it is laying ink down fairly well, the pen doesn't feel it flows well. Perhaps the pen I received is defective. I'll never know; back to Pilot HiTecs for me; they may not be as comfortable to hold, but they actually do enable me to write.
