ONYX Edition: Fearless, bold and daring. The new limited VOLCANO ONYX edition is an absolute eye-catcher - stylish, bold and daring. The ONYX color is reminiscent of black lava rock, which perfectly matches the VOLCANO's iconic shape. The high-quality powder coating makes the cone even more scratch-resistant, and the matte black makes for a strong appearance of extravagance. There's no question that the proven long-lasting quality from STORZ & BICKEL continues with this limited ONYX edition.
