"Kraze" roller ball pen , a design by Karim Rashid, comes from ACME Studio's Standard Roller Ball Pens. The pen comes with one black roller ball refill. Artist's signature is engraved on the cap band and "ACME" is on the clip. The pen is presented in a ACME metal box with a black sleeve and ACME literature. This edition of the pen comes with a sleeve signed by Mr. Rashid. Very few of this signed edition exist. Once they are gone, no more will ever be available for sale.
