If you want to add more pieces, please comment before purchasing. I use this heat shrink tubing to make the line breakers I sell, so the strength and ease of use have been proven. It can be used for DIY tools such as line breakers, golf clubs, rackets, and hammers to improve grip on the handle. To use it, measure the length of the object and cut it to the required length. Cover the object and heat it with a heat gun, hair dryer, or stove. A hair dryer is a bit underpowered, but it will work if you take your time. With a stove, if you get it too close to the fire, it may melt or warp. You can start from the point where it shrinks and heat it slowly to complete it without failure. 〇 About the outer diameter of the applicable object Compatible with diameters from 20mm to 30mm. 31mm will definitely not fit. ※ Please be sure to use it on objects with a diameter of 30mm or less. Heat shrink tubing is sold at fishing tackle stores and home centers at an unreasonably high price. I was able to import it in bulk from overseas and sell it cheaply. I actually sell products (line breakers) using this product, so the quality is sufficient. I also sell handmade accessories, fishing tools, and camping gear. If you would like a set with other items, please comment before purchasing and I will give you a discount.
