Lightweight and can be folded into a small-ish clutch bag in case I want to switch out of heels and into ballet flats (which also fold and fit in the clutch) before the wedding reception is over. I'll use another of the bags for dirty clothes in my suitcase. Handy for travel. Doubt that they would hold up long with every day "carry to work" use, but at less than $2.50/each, they're perfect for occasional use.
