Could use some adjustments
Brush has a large head, prefer it smaller with contour to get in between teeth. States that it's soft, but softer would work better. Overall, it does not seem to clean well on curved tooth surface. Brush itself appears to be of good quality if its in fact real bamboo and plant based bristles (not plastic).

Brushing your teeth now good for the environment as well as your health!
These are sturdy toothbrushes, light weight, and easy to use. I especially like the idea that I'm not contributing more plastic to the environment using regular toothbrushes.

Great value, good suds, good quality, good for the environment
Color: 5 Pack
Goodness I love these.
I moved within the last several months, and my new town and state is not as on top of recycling as my old state was. This isnt a super huge problem, but it meant I had to start finding ways to reduce my refuse. Less bottles.
So naturally I switched to bar soap. I also knew I wanted to stop using those plastic net poofs. I didnt have easy access to a washer, and I hate laundry anyway.. so washcloths arent a huge part of my life.
What was a girl to do?
Buy these.
Thats what everyone should do.
They hang nice. My soap dries. It exfoliates amazingly without being too rough. I tried another brand before this and it was *blows raspberry* 💩. Fell apart super easy, didnt suds up well.. just no.
But this one I love. The soap I bought fit just fine, but took up the whole net. I didnt like that. It didnt dry as well or suds up at all. So I started cutting my soap in half and now it works GREAT.
Warning - its not good on your private bits. Itll scratch you the heck up. You shouldnt be using anything on your private bits other than soap and your hand anyway. I also recommend harder bars of soap. Super soft super lotion infused bars dont seem to hold up as well.
If youre trying to reduce your plastic waste and like feeling amazingly exfoliated, this is for you.

This handy little tool holds my soap and exfoliates my skin gently.
Color: 5 Pack
I bought this as a bag for my new shampoo bar so it'll last longer. This bag generates a nice lather, hangs off my shower caddy, and allows the bar to dry between uses. Makes shampoo bars much more convenient. The texture of the pouch remains scratchy after 3 or 4 uses so far but it produces a good amount of lather in combination with my bar soap. Hoping it softens up with use. Very good for exfoliating! The bag does have a canvas scent to it, but once you add water and lather up the soap inside it disappears. I love this bag. We always have a bunch of soap pieces in a basket on our tub, and now we can use them till there’s nothing left! My husband's biggest complaint when convincing him to switch to bar soaps with me was that they are so slippery in the shower and difficult to use. This thing is the ANSWER! It's the perfect sudsy, exfoliating grip for bar soaps that is still eco friendly - plus, the string is great for hanging on the shower head after!

An Eco-Friendly Solution for a Zero Waste Bathroom
Color: 5 Pack
I recently purchased the E-Know Soap Bag 5 Pack, and I am extremely satisfied with my decision to make this eco-friendly switch in my bathroom routine. These natural sisal soap savers not only promote zero waste and plastic-free living, but they also provide a range of benefits that make them a perfect addition to any bathroom.
The soap bags are made from high-quality natural sisal, which is a sustainable, biodegradable material. This means that once the soap saver reaches the end of its life, I can dispose of it without worrying about contributing to environmental pollution. The soap bags are also very durable and can withstand daily use without falling apart or losing their shape.
One of the key benefits of using these soap savers is that they help extend the life of my soap bars. The bags create a rich lather while gently exfoliating my skin, ensuring I get the most out of each soap bar. The soap saver also prevents the soap from becoming soggy, as it allows for proper air circulation and drainage, keeping the soap dry between uses.
The E-Know Soap Bag pack comes with 5 soap savers, which is great value for money. I can use them for different soap bars or share them with my family members. The drawstring closure makes it easy to insert and remove the soap, and it also allows me to hang the soap saver up to dry after use.
In summary, the E-Know Soap Bag 5 Pack has been a fantastic addition to my bathroom routine. It promotes a more sustainable, plastic-free lifestyle while providing the benefits of a gentle exfoliating scrub and longer-lasting soap. I highly recommend these soap savers to anyone looking to make eco-friendly changes in their daily life.
