Natural soap

Smaller than expected. Lathers well and smells great. Rinses off easily.

A Noticeable Upgrade from Regular Soaps
Size: 3.5 Ounce (Pack of 6)
Leaves skin soft, smooth, and refreshed without dryness I’ve tried plenty of big retail soaps over the years, but this one stands out right away. The bar lathers nicely and leaves my skin feeling noticeably smoother and never dry, which is a huge improvement compared to what I used before. The scent is clean and subtle, not overpowering, so it works well for everyday use. I did expect the bar to be a little bigger, but it has held up better than I thought it would, making it worth the price—especially since I picked it up during a sale. Overall, this is a quality soap that feels more refined than the usual options, and I’ll definitely keep it in my rotation.

Works well
Size: 3.5 Ounce (Pack of 6)
I just wanted to update my review as I have had more time to review the product. The presentation is well done and in a nice looking box. Initially it did not smell the best in the box but when it gets wet it has a mild smell that is pleasant. It has a great lather, the exfoliating beads feel good, and it does work well. Great product but the smell is mild.
