Can you please help me find this sweet treat?

hello friends! I need help with finding this sweet treat, that my dad used to bring home from Beograd.

It was a hand size biscuit with a purple (possibly darker purple) packaging. It was not Milka. The biscuit itself was like two cakes and in the middle there was a chocolate filling. I remember there being two versions: milk chocholate coating and white chocholate coating. Thanks for any help!
