What the heck is this? Phoebe's Hidden Treasures

Time to play "What the Heck is it" again.
Found this kicking around the shop.
What is it?
 Does it go to something out on the floor. Ack, does it go to something we already sold??
(would hope to track down the customer)
I can't imagime it's function. Can you. Thank you in advance.

Approx 3" long
