Good soap bags
Size: Small Size
Great soap bar bag. Later is good, fit is big but that's fine way better than being too tight or small. Great value.

Fantastic soap exoplanet bags
Size: Medium Size, Size: Medium Size
Very high quality bag. I was really surprised when it arrived and I saw how well it was made. I was expecting something cheap for the price. But the quality and durability of this soap bag far surpassed the price of the item. This will last for years. The material and stitching are top of the line. I can recommend this product for anyone.

Great SLS free toothpaste
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
This toothpaste has saved me! Anytime I use regular toothpaste it makes me throw up and ever since I have started using this toothpaste. I have not thrown up one time. This is a great too toothpaste if you need a toothpaste, that is SLS free. It has a very clean taste and makes my teeth very clean.

It’s not your average toothpaste consistency
Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1), Flavor Name: Peppermint, Size: 5.25 Ounce (Pack of 1)
My teeth have become a little sensitive recently so I started using Sensodyne. Through some research, I discovered hydroxyapatite. I was extremely excited and intrigued at the idea of its ability to strengthen tooth enamel so I just had to give it a try. I first started with Risewell, but then my dentist recommended David’s due to it having nano-hydroxyapatite. I really like this toothpaste. As you can see, it’s almost all finished. I like the flavor, I like that’s it’s fluoride free so you can swallow it, and it’s made in the USA.
I’m obsessed with the packaging too! It’s got a very minimalist and modern aesthetic and it comes in a recyclable metal tube. I also love that it comes with with a little metal key to help push put all the toothpaste.
I definitely felt like this toothpaste improved my teeth sensitivity as well as helped whiten my teeth. I love that it’s so convenient to order on Amazon so it ships quickly (as opposed to Risewell).
If you’re not familiar with hydroxyapatite toothpastes then you may be surprised by the texture. It’s very loose and watery. It doesn’t really lather up the way toothpaste does. I feel like that’s one nuisance with using these natural toothpastes, but I would also say that the benefits of using it outweigh that. Overall, this is a solid product and I will definitely continue to use it as well as recommend it to others.
