A band a child picks for themselves.

A printed silicone strap with a soft-toy palette and a matte finish — the loudest of the set, and the one a six-year-old reaches for first.

A pastel print, and the quietest thing here. It is the one that reads as a bracelet rather than as a device, which is most of the argument for it.

A bright solid-colour strap with a small embossed smile and stars — cheerful detail without a printed character.
