(2) 1-meter pieces of 8mm shrink tubing. The reason we like to keep larger shrink-tubing is I am often manufacturing high current cables. It is also a lot easier to find the smaller sizes everywhere.
The applications for my use are usually are off-grid power cables and/or improvised power situations for this sort of larger gauge cable.
This shrink-tube is great for even the largest cables (up to 7.9mm I suppose.)
I am sure you can think of specific uses as well.
