They are scammers, so never believe their "Unsatisfied for Any Reason" and "100% Money Back Guarantee" claims. The guarantee is nullified the moment your first diamond is placed. They don't fulfill their commitment. They produce inferior double-sided tape. The diamonds will always be difficult to push back down because they are not permanent on the canvas. They refused to give me a refund when I complained about this problem and the missing diamonds in my kit. I have nothing to suggest. I appreciate your assistance. *COM, T-R-E-B-L-E-S-L-T-D They are currently available for you to try.
