Info:These caps were probably given away with packets of sweets produced by Stella confiserie in France. Each cap features a penguin playing a sport, along with a sweet or two. On the front of the cap it also gives the name of the sport depicted.
On the back of each cap it says "Milk Caps A Collectionner !" and "La confiserie gourmande !...", along with the Stella logo and the number of the cap. There are ten caps in the set in total, and you can see the full set below.
