A high grade borosilicate glass pipe fits into a protective anodized aluminum exoskeleton, which screws into an aluminum shell with a glass bowl. A filter screen purifies each rip. Enjoy the high quality rips of a glass pipe with rugged, elegantly geometric build that's perfect for on-the-go smoking. The 4" Pyptek Prometheus Pocket Pipe comes in five dazzling colors, and is compatible with three concentrate kits to provide a more versatile hand pipe experience.
