A word about elastic bracelets…
I’ve found, over the years, that a well secured elastic bracelet is the most comfortable and longest lasting. In addition to the knot in the elastic, I apply glue as well.
You can preserve the life of your elastic bracelet by not wearing it in water, or by pulling too roughly when you put it on and take it off.
