Sure! Found this kit from a reputable vendor: https://www.amazon.com/532pcs-Shrink-Tubing-innhom-Approved/dp/B075WR9FVL/ref=sr_1_5?crid=2D9Y44OEO8I5J&keywords=heat+shrink&qid=1564436097&s=gateway&sprefix=Heat+shrink%2Caps%2C217&sr=8-5

Amen to that! Nah you don't need any extra tools, not for private use at least. I own a heatgun but 99% of the times I'd just use a regular lighter. Can't confirm a hairdryer would work but yes, if it's hot enough :)
