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 a thread wrap grip specification.

It can also be used with other companies' spears with an outer diameter of 18mm to 11mm. ＜How to Use＞ 8 rings that are resistant to seawater and do not slip on the shaft are included per 1m.

The trick is to avoid burning by applying the heat from about 10 cm away from the red flame, and you will get a beautiful finish. Imagine broiling eel and slowly rotate while applying heat to shrink it, and you can get a beautiful finish. ＜Specs＞ Inner diameter before shrinking: 20mm Inner diameter after shrinking: 10mm Thickness after shrinking: 1cm～ Shrinkage ratio: 2:1
