Worked perfectly. Right size for my heavy wire.

### ⭐⭐⭐⭐⭐ Honey, I Shrunk The Wraps
*by J***T on May 15, 2026*

Today’s purchases are four foot rolls of both black and red large heat shrink for electrical applications. They came sealed and packed together. I wanted red and black heat shrink for my car audio installations. This purchase allowed me to conveniently buy, not only both red and black together, but the rolls allow me to cut them as long or as short as I need at the moment. I used them to distinguish between the power and ground wires since the insulation is the same color. It also made the install much cleaner looking and protected the install from shorts. These sheat shrinks seem to have an additional adhesive on the inside, meaning once they are on, they are not coming off. This is really great for securely protecting your equipment, but not so great if you have to remove them. I recently started getting into using the heat shrinks, but now that I am, I want everything to have shrink on it. These tubes are super easy to use and work on a wide range of sizes, shrinking up to four times. The quality and results that you get from these are great, and they are very affordable, making them a very good deal. If you like using heat shrink, and you are looking to get some or replenish your stock, I would highly recommend these, because they are a great value.
