The Trimline pen is slightly larger in the center than a typical Cross pen. If you like a thinner pen with a little more to grasp onto in the middle, this is for you. I hand make my pens in my shop. This pen is made with chrome metals. The barrels are an acrylic resin that I turn on a lathe to shape, sand and polish to a scratch-free shine. The color is a bright lime green. The Trimline pen uses a Cross compatible refill. Cross refills are available at larger office supply stores, on line or through my REFILLS section. I will include and ship it in a nice gift box.
