Their "100% Money Back Guarantee" and "Unsatisfied for Any Reason" are lies; don't fall for them. The guarantee is nullified the moment your first diamond is placed. This assurance is NOT upheld by them. Their double-sided tape product is subpar. The diamonds will always fight to be pushed back down from the canvas since they do not stay there. They refused to give me a refund when I complained about this problem and the missing diamonds in my kit. I am unable to suggest. I appreciate your assistance, L_*_/O_*/_U/_*/_D_/*_O_/*_U/_*_/I_*/_N.
