Uni-ball 0.38 Gel Ink Pen. This pen is accurate and precise due to the fine 0.38mm tip. The fine tip is sharp, but it still gives you a smooth writing. This is one of our favorite pen as it provides incredible ink consistency. It lasts longer and it doesn't overflow. It's great for studying and writing notes because the fine tip gives you a great flexibility with your space. The rubber section is also great for holding if you are looking to write for longer hours. It's highly recommended.
The fine tip needs to be always capped, otherwise a drop to the floor can easily cost you another replace.
