I have never seen these before. I have been using the plastic poof for years without realizing that there was a better option for my skin and the environment. Enter, Allison's Artisan Goods! While I was shopping on here for my most recent order of soap, I saw this Natural Sisal Soap Saver Bag, was intrigued, and ordered one for me and one for my Husband. After the first use I quickly saw that I have been missing out! This is so much better than using a plastic poof and pairs so well with the soap I buy from here. My Husband enjoyed using this too. He has always preferred bar soaps to liquids and this helps the soap dry well between uses and last longer. I encourage you to add this to your order and give it a try. You'll be glad you made the switch. Thank you, Allison's Artisan Goods!
