Parcel to Sweden - one nail varnish and batteries??

[Swifey]

The Post Office told me I couldn't send them, which I see on the Royal Mail website is correct, but ........ if I send it anyway will it get stopped?

I've just googled it, and they are prohibited, and sending is a criminal offence, items get scanned and could be destroyed.

Seal them in a plastic bag and send them any way. I would.

Why would you send two flammable, combustible items together and think its ok?
