The tubes shrink quickly and evenly when heated, providing a secure and durable seal. The pack is versatile and well-organized, though the quantity of certain sizes to be unbalanced based on specific needs. Overall, it's a handy and cost-effective kit for me.

Very nice value pack. Has variety of sizes for different applications. Carrying case is handy and convenient. I recommend.

Very useful for restoring/repairing charging cables, especially when you have kids with devices.

Nice kit!

it's heat shrink, works as it should.

Great.
