Set of eight vintage Napier Goldtone Cheese Mice Appetizer Hors D'oeuvre Servers

Set of eight vintage Napier Goldtone Cheese Mice Appetizer Hors D'oeuvre Servers in their original box. These servers, model number 604, were designed by Napier in the mid-century and are made of gold-plated metal. Each server is shaped like a mouse with an extended tail that acts as a pick for cheese or other appetizers. The box is labeled "HORS D'OEUVRE SERVERS" and "Napier". The set is considered rare, especially in new condition, these have never been removed from box. I didn't remove for pictures.  The servers are approximately 2.75 inches tall and weigh about 20 grams each. The original box measures 5.75 x 3.25 x 1.25 inches.
