Product review (4 stars): they work fine. They are strong enough to rinse off when ...
The photo  describes this item as "Heavy Thick Quality." It is not. It is very thin. That being said, they work fine. They are strong enough to rinse off when they get dirty, but they are not strong enough that if they get very dirty you'll be able to scour them clean.

But for an item that costs under $0.34 each, and for some reason cannot be found locally, they're four star fine.
