Absolutely Worth The Money
Scent: Graphite Gray_4 Pcs
These things are great. The soap stays in the bag and it acts as a natural exfoliant. It's not harsh and it works for my sensitive skin. I have psoriasis and this thing does not agitate it at all. I've never owned a bag for my soap but, it really works. The cost was low and, now this is how I shower. Much simpler than working a loofah and all that liquid soap together. I would recommend to a friend. Great value. The length is big enough to fit any bar of soap known to man. There's no soaps gun build up and no smell to them. They just smell like the soap that contains them. They feel durable and I'm positive I couldn't rip one in halfway hulk Hogan entering the wrestling ring.

Perfect for the men in your life!
Scent: Graphite Gray_4 Pcs
Honestly this is a great product for anyone but I bought one set to give to my 17yr old nephew who loves using the Dr.Squatch soap bars. The other set I bought for my soon tonbe 12yr old son. I bought him a charcoal soap bar for exfoliating & the bag is perfect for him. Lathers up well & has just the right about of coarseness to it to help scrub dry skin away. The bar keeper we use for my soap or honestly for my razor that seems to keep falling off its holder. The bags are quite a bit bigger then I would expect for the fact a bar of soap goes in it. It would fit easily 2-4 soap bars. Not sure why that much room is needed but none the less, great product

Bigger then I thought it would be.
Scent: Graphite Gray_4 Pcs
The only complaint I have is that in the picture it looks like its about the size of a normal bar of soap. In reality though you could fit like 4-5 bars of soap in this thing, it's way bigger then I thought it would be, in fact it's huge. At first I thought this was a negative thing, but after using it a few times I realized that with the insert they give you it's fine and the soap basically stays in place because of the insert. Quality: Seems to be decent quality Value for money: Yeah I would say it's a decent value Roughness: Doesn't seem too rough

A Winter Essential I Keep Reaching For
Scent: Graphite Gray_4 Pcs
I love these body scrubbers, especially now during the winter season when exfoliating dry skin is a must. The texture is just right and scrubby enough to smooth out rough spots, yet gentle on sensitive areas. I also appreciate how the pouch holds leftover soap bits so nothing goes to waste. The graphite gray color looks sleek in the shower, and the lift pads help the scrubbers dry quickly and stay fresh. They lather beautifully and make my skin feel noticeably softer after each use. This set has quickly become one of my favorite simple self-care upgrades.

Durability and cleanliness
Scent: Graphite Gray_4 Pcs
I use the soap saver pouch everyday. I honestly don’t use it for what it’s intended for besides cleaning my body. I use body wash instead of soap bars so it defeats the purpose. But this review isn’t about that. It’s more about the durability and feeling of cleanliness after using it. I don’t need to apply a lot of pressure because it is abrasive. So a light rub with body wash does the job. And if you’re to use it on your face like I do, you have to use even LESS pressure because face is MUCH more sensitive. I even wash my hair with it (I’m almost bald) but I have dandruff. I don’t have to use the shampoo anymore after scrubbing my head with this. Anyways I feel the soap savor pouch works very efficiently in getting all the dead skin off my body. I love using this product over a washcloth or those other products. WARNING: Not good to use for sensitive skin. Product is abrasive and will irritate sensitive skin.
