These blanks are totally scrap. I bought a 25er Spindel and after two firing tests, both of which have failed, gave up. Shame, because the problem has been already described herein diverse. One should stop but read the reviews, at least the negative, and then decide only. But now an extra praise for the supplier TOMDAX. The have the trash taken back without hesitation and delivered me blanks that can be burned properly and play. As you get while only 10 for the same money, but the investment is worth it. The Rhinelander says "Wat nix kost och is nothing." Very big thanks to TOMDAX, who took care of really serious and knowledgeable about the problem solution. KHD
