Glo Stix are made from luminescent for better visibility in dark locations
The 3/16" diameter Glo Stix are more flexible (4-14" minimum bend radius) and are best for working around corners, in walls, etc.
Clear non-metallic storage tubes keep the Glo Stix " charged"
Sturdy steel threaded connectors allow interchangeability of different size Fish Stix and Glo Stix (The 540-6 is a single stick with a fixed bullet nose on both ends)
