User Summary Munchkin Sherpas are Sherpa pen holders with Munchkin-related artwork and special rules for Munchkin games. Currently there are two versions, one with a fantasy Munchkin theme and one with a Munchkin Zombies theme. They were made in very limited quantities, were listed at high prices ($50 for fantasy and $40 for zombie), and sold out quickly. As a result, Munchkin Sherpas are among the rarest Munchkin promo items. Other Part of the Munchkin series.
