Spend a few minutes with the Rotring 600 and you'll understand why it has been so frequently requested at JetPens. This highly sought after product has a weight and feel that represents what a professional drafting pencil should be to many people. It has an all metal brass body, traditional knurled grip, fixed 4 mm sleeve, lead grade indicator (with knurled metal casing) and clip. It has a very technical look and will appeal to engineers for its solid construction and lead advancement mechanism. The guide pipe gives an excellent view of the lead. The pencil has an 8 mm diameter grip and 9 mm hexagonal body shape. The subtle change in body shape links this modern drafting pencil with its wooden pencil ancestors. The top cap holds an eraser and also features the iconic Rotring red circle.
The Rotring 0.35 mm is equivalent to the standard 0.3 mm we are accustomed to and accepts 0.3 mm lead. The 0.35 is a German distinction that recognizes that the 0.3 mm pencil lead diameter is actually closer to 0.35 mm.
