Each of my handmade products comes with a durablitity guarantee. If anything breaks on the rosary or bracelet, you may send it back to me at anytime and I will replace and/or fix the item and send it back at no extra charge. The clay beads are very strong and are able to withstand a significant amount of handling and praying :) I try to make the rosaries and bracelets as strong as any rosary or bracelet can be, however, extreme tugging or pulling on the string of the rosary or bracelets may cause the rosary or bracelet to come undone. In the unfortunate case of this happening, or a bead breaking, please send the item back and I will fix it and return it at no extra charge.
