Jetstream 4&1 Four new pens in a set. * Green 0.7mm * Navy 0.5mm * Light Pink 0.5mm * Gold 0.38mm They write smoothly, and since they're a mechanical pencil & ballpoint pen combo, they're really convenient to have. The quality is also quite good, and I keep one in my bag. They last surprisingly long, and since I have a lot in stock, I'm selling them at a bargain price.
