Posted on Google Sol HarterTrustindex verifies that the original source of the review is Google. Fast turn-around and lead times (For shipping from overseas) but very poor quality. First order around 1/3 of the boxes were soiled and unusable. The second order they switched out the stock to be 1/3 of the specified weight, making these essentially unusable.
