Its sturdy barrel and tip provide durability for heavy use, while the refillable design supports sustainability. Popular among artists and writers, this blue-black pen set is a rare find in the US, combining professional-grade performance with sleek, reliable style. ## Description The Uni Signo DX (UM-151) is claimed by some to be even better than the Pilot Hi-Tec-C! It comes in 0.38mm tip size. 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. Review: Bolígrafo de gel de alta calidad - Para mi es el mejor en su clase. El color azul-negro es excelente, la punta de .38mm es ultra fina para escribir letras pequeñas o escribir en letra manuscrita en renglones delgados. Review: Product as described, good price - The UM-151 is a pretty well-known pen so there's not much left to say about it. I've been using these for the past seven years and the only issue I've ever had was that they will stop working if dropped on the head. The only factor is price and shipping and those were both good. ## Features - The Uni Signo DX (UM-151) is claimed by some to be even better than the Pilot Hi-Tec-C!
