We will ship in "purple." If you leave a comment, we can change it to one of the other six colors. # Spear Anti-Slip Grip List Commonly known as "thread wrap grip." Many people are hesitant because they think, "Can I do it neatly?" when it comes to thread wrapping. This allows you to easily make your spear into a thread wrap grip specification. You can rest your hand or fingers by hooking them on the thread-wrapped part. Compared to just attaching an anti-slip, you can reduce the necessary grip strength when the rubber is stretched by nearly half. Your hand and fingers will firmly grip the shaft. We can accommodate multiple purchases if you leave a comment. ＜Size＞ It will definitely fit the size of our spears. It can also be used with other companies' spears if they have an outer diameter of 18mm to 11mm. ＜How to Use＞ We include 8 rings per 1m, which are resistant to seawater and do not slip on the shaft. Determine the ring position on the shaft that will be the raised part. This is the place on the shaft where you grip when pulling the rubber. Cover it with the anti-slip tube and shrink it with a gas burner. Search YouTube or the internet for "heat shrink tube" and you will find many videos. Basically, it is shrunk with a heat gun, but our recommendation is a gas burner for barbecues and outdoor use. The trick is to avoid burning it by applying the heat directly, so shrink it with heat about 10 cm away from the red flame, and it will finish beautifully. Imagine grilling eel kabayaki, and slowly rotate it while applying heat to shrink it without burning it, and you can do it beautifully. ＜Specs＞ Inner diameter before shrinkage: 20mm Inner diameter after shrinkage: 10mm Thickness after shrinkage: 1cm～ Shrinkage ratio: 2:1
