I received this very odd product through a blog giveaway. Those prune-looking things are fruits that grow in Asia. They contain a soapy chemical, and you can use them to do your laundry.
I actually used some. I did a load of towels. You throw a few shrivelly fruits in a bag and toss the bag in the wash with your load. It worked fine.
Pros: works just fine, all natural, kinda fun. Cons: not available locally, expensive, I don't know how well they work on very dirty laundry. Conclusion: they're fun to play with, but I don't think I would actually pay for them. I'll be sticking to my homemade laundry detergent, which I love.
