Good for Both You and the Environment!
I really love the dedication to the environment that I find in these poufs. That is genuinely refreshing since I suspect many of my previous poufs were made from plastic-type materials.
And these make change easy! The poufs feels nice on your skin and I really like the silky, orange ribbon. Very chic!
These create as grand a lather as any similar product! And the dry out completely and well.
This is such an excellent collection: good for the environment and good for your skin! Highly recommended!

Super rough!
I purchased these as a gift. When I received them and noticed that they are super rough and hard, they are beyond exfoliating. I can't imagine gifting these to anyone. They description is misleading and no where is it stated that you are unable to return them! I am incredibly upset that I can't return them and purchase something more giftable.

Way to harsh
I’m not someone that has sensitive skin, like at all. I even exfoliate every week or two with one of those super course gloves that legit beads up your dead skin. When I first came across these Cleanlogic I thought that they were like a washcloth material but in poof form, I actually got them thinking my son would love them. Once I got them and felt them I realized that they were way to course to let my 8 year old use. But since I generally love exfoliating ones like these I figured I would love them.
Unfortunately these are way to harsh even for me. You can barely touch them to your skin without feeling like they are going to leave scratch marks! I even thought maybe they needed to soak in water for a bit and that they were just stiff. Nope. So unfortunately for me these are a pass.

Sensitivity and gum issues be gone
Flavor Name: Mint, Size: 3.4 Ounce (Pack of 1)
Great toothpaste! I've been incorporating more nano hydroxyapatite into my oral care routine, and I was pleased to find this with a verifiable 10% concentration. It's pricey, but worth it in my opinion. It only takes a tiny amount to do the job, which is actually surprising considering it doesn't foam. I'm prone to canker sores, and this prevents them. The taste is fresh and not too overpowering. It's great if you have sensitivity, and definitely reduces or eliminates it. I had professional whitening done, and zero sensitivity because of this. It's great for preventing stains on your teeth (huge coffee/tea drinker), too! And, if you have gum issues, this will help tremendously. My dentist was very pleased at my appointment this past week. Will continue to use, and recommend to others.
