Uni Jetstream 4&1 Pen/Pencil
Uni’s multipurpose writing instrument combines four different ballpoint inks with a mechanical pencil. It has smooth-flowing 0.7 mm red, green, blue, and black pens on board, as well as a 0.5mm pencil lead for those times you need erasable writing. There’s also an eraser hiding under its back cap.
