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.

Work as intended not like the cheap one that barely shrink these one shrink like they should without having to burn them.

Decent quality for the price

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

Nice kit!

it's heat shrink, works as it should.
