The bracelet is 2 cm wide and with not stretched rubber band about 17 cm. This rubber band is about 5 cm long part of the bracelet. It may be extended by more than 4-5 cm, then it would but already sit very tightly. Even a narrower wear (at arms with less than 17cm circumference) is possible, but then forms a possibly long uncomfortable loop of the rubber band.
My daughter fits the bracelet very well, and she finds it enjoyable. The material is a nylon fabric and makes a high-quality and stable impression and is likely to be pleasant even after prolonged wear and, if necessary. When wet. Even the Bumblebee Design like her good, but that's a matter of taste. But it is really cute. ;-)
Under the Velcro is a hole into which you can slide the ID cards so that only poking out a short clip with inscription "ID". The opening is then covered with Velcro.
There are included 2 of this ID card. They are preprinted each 2.5 x 7.5 cm in size and on the front and back with 5 or 6 lines and the areas of "information", "name" Tel "DOB", "Medications" and "Allergies". The cards are made of plastic, so it may not be easy to find a pen that keeps reliable, long-term it.
Both the bracelet and the tiles are waterproof. If the child is old enough to point to themselves on the cards, this is a simple solution to not getting lost. But even outside of the rather eye-catching bracelet is "Little Life ID" it so that even with lost baby fast help should be possible.
Overall, a very pretty, practical, high quality and safe solution, for example, to go with children in good conscience sometimes in larger crowds and not constantly watch or fear to have.
