I need some sort of soft elastic binder to hold closed laptops and books, or bind together things like stacks of DVDs or bundles of pens. Many of these items would be damaged if I wrapped a metal spring or a bungee cord (most have metal hook ends) around them. When I have used rubber bands they tend to break or lose elasticity if used (or even stored) for more than a year.
Storage conditions are indoors (closets or shelves), or garage (slightly worse temps, but never in sunlight)
My highest priorities for the qualities of the binder are:
adjustible/flexibile (allows using on different sized objects)
visibility of items wrapped (to avoid having to label them)
Durability (lasts a couple of years, prefer longer)
re-usability (hand-in-hand with low cost)
economy (low cost is better)
The last three (long lasting, reusable, low cost) are related in that something long lasting and reusable enough can have a higher price for the same value.
