Thank you for viewing. This is a set of Pentel's Hybrid (Hybrid K175) gel ink pens with 0.5mm black and red ink, and a clear barrel. These are cap-type gel ballpoint pens. Both pens are still able to write, but sometimes the ink may skip. These products are now discontinued. The Hybrid K175 was released in 2004 as a model that writes lighter and smoother than the conventional Hybrid, and it won the Good Design Award. It features a flat clip and a rubber grip.
