Mid-meeting, your pen's ghosting. The one you grab next is the same. Boring, right? The Uni-ball Signo RT 0.5mm doesn't do that. Water-based gel ink lays down a clean line first time, every time — no smudging on the page before you've flipped it. The rubber grip means your hand isn't cramping by paragraph four, and the twin ball ink control keeps flow steady from pen one to pen twelve. Twelve in the box. Stick one in each drawer
