Personally it’s important for me to use the best qualities available for the bracelets. For each bracelet I use wax-string which is very beneficial, because it’s durability of the colors through which it lasts much longer and is not so much affected by the sun or other daily influences. But even, if it’s very long lasting it should not come in contact with water, because it will loose his wax and with this his durability. Like the metal parts will change their appearance the more influences they come in contact with, especially water.
