Product Details
This 8-pen set includes black, blue, red, violet, light blue, pink, orange, and green.
The Uni Signo DX (UM-151) is claimed by some to be even better than the Pilot Hi-Tec-C! It comes in 0.28 mm and 0.38 mm tip sizes, comparable to the 0.25 mm and 0.3 mm sizes of the Hi-Tec-C.
The barrel and tip are a bit sturdier than the Hi-Tec-C, which might explain why converts love them. Users can enjoy clean and even flowing lines, and the strong tips can withstand all the heavy handed writing you can offer.
Like all our other pens, the Uni Signo DX is highly sought after by artists and writers alike, but difficult to find in the US.
Ink is waterproof and specially formulated to have low viscosity so that it won't spread on the paper.

Darn, I was just about to order these, and they're sold out. Please restock! ^_^ I LOVE the couple
of DX UM-151s that I have - now I need them in more colors!

i really like the colour and the ink of the pens, but i find that it is easily ruin ( i don't know
how to say this sorr for my bad english. T^T) because of its thinness. for instance if someone
drops them, the ink won't be able to come out properly, other than that it's a really good pen to
use!

i just got these pens and I love them! The package said they come in certain colors so i order 2
other colors, but they ended up being the same as in the set! I could have gotten more colors!
they never leak and write really smooth.
