The Rite in the Rain Clicker Mechanical Pencil may well be the last pencil you'll ever need to buy. True to the Rite in the Rain brand， this pencil is tough， reliable， and writes no matter what. A hefty 1.3 mm lead is not only tough， it writes smoothly on Rite in the Rain and other papers. This versatile tool can write in a notebook just as easily as it can mark lumber or drywall. The tough knurled grip， nib， and mechanism are brass. The thick， dark black 1.3 mm lead won't snap at the tip or break in the shaft. Durable ABS (Acrylonitrile Butadiene Styrene) barrel survives through the toughest conditions. Refills for erasers and thick leads are available.
