Gemini Silicone Rig Tubing,
1mm, The main use for 1mm silicone is sliding stop knots on a snood line, a moveable bait stop for instance. 1.5mm, With the increased internal diameter, this is more for use on the rig body, again mainly for sliding stop knots. It can also be used as a stand off on your hook lengths/snoods to help prevent tangles.
