It is plastic but of good quality. Quite lightweight for people who don't want to hold a heavy pen. It is a ballpoint pen that accepts Parker-type refills. It comes with a Schneider ECO 725M refill in black, which is quite good. Personally, I have been using Schneider and Schmidt refills for my Parker, Waterman, Retro51, and Lamy pens for a while now (buying from skroutz offers a better quality/price/durability ratio). To change it, you unscrew the front part.

In the hand, without measuring it, the weight is the same as the Pilot Explorer. Similarly, in thickness, the Schneider is slightly longer.

It is quite "clicky" without being annoying, and the springs are as hard as they need to be.
