Is this a single loofah sponge or a two pack?
Roughly how long would one of these last?
It depends on what you use it for and how much it is used. If you only use it to wipe down surfaces and plates then it should last for months. If you use the sponge to wash knives and sharper kitchenware it can last about a month or two. But the good thing is that it will fully biodegrade, unlike plastic kitchen sponges!
