This is exactly as described and what I needed to prevent heat creep from my hot end to the thermistor on my 3D printer. I no longer am replacing thermistors regularly with proper protection in place. There is a lot of tape that comes with the order. I could have paid attention and ordered something a little wider, but this works well enough for my needs.

Makes patching wiring a breeze

I use this for repair job on an antique light fixture in my Victorian home. Work like a charm. I’ve got plenty left over and I have a feeling I’ll be using it in the near future.

Super sticky!

I find all sorts of uses for this tape. It’s super sticky on both sides and could be used for a wide variety of applications. Maybe an eighth of an inch thick, which works well for uneven surfaces. My last use was hanging mirrors on the wall, and it worked great.

Adheres only to itself.

This stuff will only stick to itself! Can't put down a layer and hope it adheres to a surface.
