Message from the sea: Tiny Tuesday

Washed up on the beach
An island with sparkling sand
Message from the sea

Is it a cry for help or maybe a love letter with a tiny key to someone's heart?

All the elements are very tiny:
glass bottle: 10.5 cm/4.1 inches
Message: 6.5 cm/2.5 inches
key: 2 cm/07 inch
So really, any one of them could be considered tiny enough for Tiny Tuesday. Thank you to Pinkhairedlady for hosting.
