Bought this fo rmy 16 month old who has a severe peanut allergy. It was too big, but I plan to take it to have a few links removed and have the back of the plate engraved. Great quality, sturdy (I tried to pull apart as a child might do, but it held up). I have looked at other medical bracelts that were 3X more expensive, but they all do the same thing. great product for a great price.
