When you're spending your day in the field exploring forests and identifying plants and animals, the Rite in the Rain Mechanical Pencil allows you to jot down your observations no matter the weather conditions. Its strong resin barrel fits comfortably in your hand so you can write and sketch as you move from one plant to the next while the patented tip expands so that the lead doesn't break or wobble as you hurriedly write down your thoughts. Multiple included refills and two extra erasers ensure you're prepared for your day in the field, rain or shine.
