what was the solid perfume called, that was in a small metal apple ?

[Guyzie]

I want to get this perfume for my mum for xmas because she said to me with fond memory's how she owned one as a teenager, She described it as being an apple shape that was made out of metal with a solid perfume inside, you dab'ed the perfume on your self with your finger, apparently to get to the perfume inside the apple it unscrewed into half, she also mentioned she wore it on a chain as a necklace pendant. She owned one around 30 years ago. What was it called? do they still exist? and where can i get one if they are still around? cheers peeps
