Giant sequoias are the world's grandest trees and largest living things by volume. The Monteverde Giant Sequoia may not be the world's largest pen, but it will be appreciated by those who prefer a substantial writing instrument. The solid resin barrel's striped pattern in earthy tones reminds us of the massive trunks that greet visitors of Sequoia National Park, but this pen doesn't want to sit still! Ergonomically designed, Sequoia feels poised and balanced in the hand and begs to be used daily. The fountain pen fills via standard cartridge/ converter (included) and the large SS nib is available EF, F, M, B and 1.1mm stub point sizes. The matching twist action ballpoint tapers elegantly to fit perfectly in the hand and fills with standard parker style refills. Polished chrome accents are durable and scratch resistant and decidedly minimalist on this design, letting the beauty of resin shine through.
