The Opt pencil is a quality instrument available at a fraction of its potential price. The sales slogan for this line in Japan is "Dress up!", and it was designed to accompany business people and travelers. It features a broad body for an ergonomic hold, a push clip that can be used to clip this pencil onto thicker objects, and a shaker function! This means that you can just shake the pencil and the internal weight mechanism extends the lead for you! No need to click (though pencil includes this feature)!
