Convinced to make the switch
Style: Citrus
Love this soap. I was using Jukebox, but I'm making the switch. Crate 61 feels better on my skin, the bars last a little longer and the 6 pack is $15 cheaper than I was paying for 6 bars with the Jukebox subscription. I get extremely dirty at my job so I tend to go through soap faster than the average women. Jukebox bars would last me about 4 days. These will last 6 or 7 days. Jukebox bars were a definite upgrade from body wash, but it would irritate the sensitive areas. I don't have that issue with this soap. Jukebox bars smell nice in the shower, but I feel like the scent didn't last beyond that. Crate 61 leaves a pleasantly subtle smell on my skin after showering. The only benefit with Jukebox is that you can choose the individual soaps in your 6 pack, rather than selecting one of the collections.

Good smells, better clean
Scent: Assorted, Scent: Assorted
This Rinse & Robust 4-pack men’s soap is a great option for anyone looking for a refreshing and rugged scent in their daily routine. The bars come in four distinct manly fragrances—Santal, Leather, Charcoal & Clove Oil, and Cedar Citrus—which provide a long-lasting clean feeling. Made with natural ingredients like oat, green tea extract, and coconut oil, these soaps offer both exfoliation and moisture without harsh chemicals like sulfates or parabens. The 4-in-1 design makes them versatile for body, hands, face, and even shaving, making skincare simple and convenient. Packaged in a sleek gift box, this set makes an excellent gift for any man who appreciates high-quality grooming products.

Good product
Scent: Assorted
Good soap set I like the smell and the 4 pack last a good while. My only complaint about the soap is at the end it was soggy soap and hard to get it to dry. I will give the other bar a try if it does the same thing I might not be using this.

Scent: Assorted
I like this soap. It has great scent with adequate strength to support feeling fresh and clean. This soap easily cleaned my skin and removed body oils without making my skin dry or itchy or uncomfortable in any way. I also appreciate the cost is more friendly as compared to similar bar soaps with popular brand names.
