I got a pack of these in an Armour All gift set like they make at the holidays. I liked the sponges so much, I googled until I found a way to buy them online b/c they are not in the usual suspect stores like Walmart or Target. Quite simply, I love how much suds they produce and if you don't rinse them excessively at the end, you can get several uses from them. The 'netting' that goes over the sponge is great for removing bugs and tar. Believe me, I'm as surprised as anyone here!
