How do you open the Bacardi solera bottle?

Whe you open the lid it has a plastic cover with marbles inside. I ended up breaking the plastic and pulling the marbles out to drink my bottle. any help?|||Just leave them in there. Theres nothing wrong with the marbles being in there. they are for looks. If you are drinking straight from the bottle then just empty the bottle into another container and pour it back in without the marbles.
