The armor is made from beads of various materials including glass.  They can break.  Each piece is double stringed for added strength but they can still be snapped if stretched out beyond normal limits.  Take care to remove bracelets before changing clothes so as not to snag them.  Hand dyed beads can fade with time and exposure to water.  Some discoloration from oils from your skin is normal as some beads are porous and only add to the unique look of your piece.
