We will ship in black. If you leave a comment, we can change the color. This is commonly known as the "thread-wrap grip." Many people are hesitant to do thread wrapping, thinking, "Can I do it neatly?" This allows you to easily convert your spear into a thread-wrap grip specification. #Spear Anti-Slip List You can rest your hand or fingers on the thread-wrapped part. Compared to just adding anti-slip, you can reduce the necessary grip strength by nearly half when the rubber is stretched. 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 the outer diameter is 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 for "heat shrink tubing" on YouTube or the internet, and you'll find many videos. Basically, you shrink it with a heat gun, but our recommendation is a gas burner for barbecues or outdoor use. The trick is to avoid burning it by applying the heat directly. Shrink it with heat about 10 cm away from the red flame, and it will finish beautifully. Imagine grilling eel kabayaki; slowly rotate it while applying heat to shrink it without burning it, and you can achieve a beautiful finish. ＜Specs＞ Inner diameter before shrinkage: 20mm Inner diameter after shrinkage: 10mm Thickness after shrinkage: 1cm～ Shrinkage ratio: 2:1
