Jewelry Birds

Information on the Fairy Tails Jewelry Birds or Teeny Tiny Tails is hard to come by. About 1"tall, They were intended to be worn on necklaces, bracelets, rings and headbands. Unlike their larger counterparts, they bore no symbol. They can be found in lavender, green, yellow, orange, pink and blue. The pink and blue birds come with 2 different colored hair plumes.
When they weren't accompanying their human friends, the jewelry birds had minuscule perches to rest on. The carded Jewelry birds pictured are from the Netherlands. The text is in French and Dutch. If anyone would be willing to translate the information into English I'm sure everyone would appreciate knowing more about these tiny FairyTails.
