A metal whistle on a braided cord you can wear round your neck or round your wrist. It comes on a blister card from Kim'Play, the toy brand of the French manufacturer Cofalu.
Children use it to play referee: a game of football in the garden, a relay race in the playground, a made-up obstacle course where somebody gives the starting signal. Along the edges of the card run sports pictograms that call up exactly that use.
The cord is supplied in varying colours, so you cannot pick in advance which one you get. The whistle itself is always the same metal model, light enough to hang round a neck all afternoon.
A small extra for a sports day, a children's party or the dressing-up box, and the kind of thing there is usually one too few of at home.
