about this thread, and the previous, since my product was not mentioned too kindly:
We do offer our
clay in a container, when it's purchased in our professional line. The bar size is 240 grams.
Our clay (along with every other product we make) has a satisfaction/money back guarantee. Very few bars come back (even some in the wrapper with comments that the clay didn't do anything). Far more
clay bars are stolen out of the box than come back from satisfaction returns. I believe every manufacturer listed offers a similar guarantee. I fail to see how this brand's is better than any other's.
"Zebra" clays (black and white stripe) have been around some time. All of the ones I've seen have been quite aggressive, and the white is a silicone caulk type substance. Due to their aggressiveness, they're inappropriate for consumer use, as they will mar the surface.
I don't think it's fair to compare the cleaning ability of a mild consumer-friendly bar, no matter the brand, to an aggressive bar - that's like comparing a Z06 to a Cavalier.
I've also not seen or heard any complaints of our bars crumbling under use.
