Sometimes Size Does Matter
Scent: Alpine & Spice, Scent: Alpine & Spice
Let me just get this out of the way now the soap itself smells decent, nothing wrong there. I only wish I got another cent. Not that this one smells bad it’s just it wasn’t my cup of tea. I’m mostly disappointed about the size because I’ve been through this before. The soaps themselves are not big enough to fill out the box as you can spot in some of the pictures and video. I honestly feel like the soap size was different in the pictures of the customer reviews that I saw. Each bar may last me a week and a half and that’s with a soap saver. To be honest, the box that it came in would fit two decent size soaps if they filled out the box.

An excellent value for a luxurious long-lasting daily necessity
Scent: Lavender
Lovely soap with a pleasant fragrance and great lather. Real lavender buds give it an exfoliating quality without any roughness or redness. Product lasts and lasts so this crate is a true bargain. It truly is a 5 star product - I would give it 6 stars or more if possible. I use it for facial care and am very happy with the luxurious sensation of self-care every time.

Very good bar soap
Scent: Alpine & Spice
I have been using this bar soap for about two years now. I continue to use it because of the ingredients, the way it’s manufactured, and because of how it feels on my skin in the shower and afterwards. I have only used the “no grit” flavors. The scents are ok, nothing special or exciting. Some of them barely have any scent whatsoever, and some of them have a mild scent. But none of the flavors I have tried have a strong scent, and none of the scents are bad or offensive. The lather is excellent really good lather. My skin always feels clean, hydrated, and healthy after showering with all flavors of this soap. Love this stuff. Crate 61 customer support is excellent.
