Textured METLLC VNYL TEXTR Onyx

In the description, it says “3 count,” are there actually three separate rolls in this? Or is it just one roll?

Is the textured metallic, when put on a mug, microwave safe?

Does this already have adhesion on the back? I was going to use it to cover an appliance.

Is it Dishwasher safe? And how long does this last for on a bottle?
