These is a rare Goodwill Zig-Zag Wave pen and pencil set. They are matte black and have been used. They are missing one of the rubber bands that holds the lucite secure for it?s protection and aesthetic casing. It is signed by Sensi pens, was sold at Dillards, modeled Labo 1990 ? and somewhere along the way, picked up a cult following. These are exceedingly rare and other sellers are asking upwards around $500 for the set. We have this Preowned set and a new set available. Feel free to grab both and save on shipping; plus we?ll cut you a deal! Shipped via USPS Ac/Dc Goodwill Zigzag Wave Matte Black Ballpoint and Mechanical Pencil - Rare USED. Condition is "Used".
