I hate when you gragva sponge and your hands smell. Yuck. Bought these because they promised not to get stinky and so far so good. They are not as thick as the ones we are used to but that doesn’t matter. They work great and did I mention no sponge funk.My order wasn't the wavy shape I had hoped for. I got a box of rectangles. Otherwise a sponge is a a sponge, the pack was very very compressed and easy to store and stock. Would recommend if you store lots of household supplies. Value for money would be better if they sold this in larger packages.Para fregarToo thin. About half the thickness of Williams Sonoma or Trader Joe’s pop-up sponges.I like how compact they are until you wet them for the 1st time.I like they are completely dry with no odor let alone mildew odor like regular sponges.They expanded like a regular sponge with a minute or less.These sponges are super thin until they are wet and then they expand. They work well for cleaning shower floor and countertops. They don't seem to shred like other sponges do after the first couple of uses.If you're looking for a more green alternative to sponges, this is a good option. There's definitely a novelty to the growth aspect of it. Performance wise, it's just a sponge. Wouldn't be great for heavy duty scrubbing, but it does the trick. There's 16 in a pack and it stores really well. No weird odors or anything like that. Don't know that I'd go out of my way to buy this again, but that's more of a personal preference than an issue with the product itself.Pretty standard sponge I would say, possibly a little thinner but no big deal. I was impressed with the packaging: all 16 sponges fit into a box a little bigger than a standard deck of cards! Definitely great for travel or camping.I love that they are biodegrable. Great for the environment!
