I purchased 2 bracelet stacks (433), 1 for my granddaughter for Christmas and 1 for myself. So far, my granddaughter is very pleased and wears them 24-7. I really like the look but do not wear mine all the time. The quality appears good as many have stated in other reviews but only time will tell if they will withstand the 24-7 wear by a 14-year old and the on-off occasional wear of an adult. I cannot comment on the anti-tarnish or if they will stretch-out when you take them on/off more frequently as we just haven't had them long enough to verify the durability.
