A heat gun set to 150–200°C is ideal. A lighter works but requires careful, even application to avoid burning.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use a soldering iron to shrink the tube?\u003c\/strong\u003e\u003cbr\u003eA: Hold the soldering iron close to (but not touching) the tube and move it along the length. Direct contact will melt and damage the tube. A heat gun is strongly recommended for best results.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What sizes are included in the 800PCS kit?\u003c\/strong\u003e\u003cbr\u003eA: The kit includes multiple diameters (typically 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm) in multiple colours.
