Available in 9", 12", and 15" sizes, this straight-tube design offers three height options with the same twisted appearance.

The iridescent finish reflects different colors as light hits the glass, while the spiraled body creates a textured, eye-catching silhouette. Each size includes a removable 14mm downstem and matching glass bowl, making it a complete water pipe setup.
