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, measure the length of the object and cut to the required length. Cover the object and heat with a heat gun, hair dryer, or stove. A hair dryer may not have enough heat, but it will work if you take your time. With a stove, if you get too close to the fire, it may melt or warp. Start from the point where it just begins to shrink and heat slowly, and you can 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 unreasonably high prices. I was able to import a large quantity from overseas and sell it cheaply. I actually sell items (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, I will give you a discount if you comment before purchasing.
