Robbie Busch (DJ McBoing Boing) and Arognaut Resins will drop the fourth wave of Busch’s El Diablo resin later this week. The five figures in the wave (#16-20) will include the Emerald City Diablo the Straight Outta Hell Diablo and three surprise editions. As with prior releases, each El Diablo comes with a matching Skully accessory, a bonus original mini paintings, a certificate of authenticity, and hand-painted packaging. We’ve said it before and it bears repeating – Robbie’s will gone to serious lengths to make something special for fans and collectors.
