Vintage Pewter Heart Teapot Perfume Oil Diffuser Key Chain

Teapot: 1.5"x1.5" - Total Length: 3.75". Vintage keychain/mini perfume bottle, I believe made from pewter (it has some weight to it). The keychain is a tea kettle with a heart design. When you screw off the top of the tea pot, revealed is an inner glass bottle (does not come out) with a small application stick. Can also be used for essential oils. No makers mark, unsure of brand or specific age!
