@Helios-

FT has 18650 heatsrink wrap in a many colors.
$1.18 clear See “Available models and parts” for other colors. Blue is $0.84
You can shrink it with a lighter.

You could try clear packing tape folded over the edge. New wrap will be best tho.

+1. Re-wrapping is easy, and takes about 5 minutes or less (per cell). I use my hair dryer with great results.
