Description This amazing Tornado Acrylic Silver Lining rollerball features 51 shades of gray tones that are intermixed to create the acrylic barrels with a supercell pattern, polished to a gloss finish and completed with a stainless top disc and chrome accents. Each one is packaged in a tube featuring B&W photography by Retro51 collector Mike Gfeller with silver foil embellishments. Please note that each pen has a slightly different pattern. The textured knurl-top twists to extend and retract the smooth-flowing rollerball refill.
