How Do You Open This Bvlgari Perfume Bottle?

Someone gave me this recently:

I was delighted. I mean, which gal doesn't like to receive perfume, right?

But when I opened the packaging, I realised I don't know how to open these two bottles!!!

Since when a simple thing like opening a perfume bottle became so complicated? What happened to simplicity?

The designers wanted to create something impressive and futuristic; but they forgot about practicality and simplicity.

Can someone please tell me how to open these darn bottles? I don't want to damage them cause they are too pretty to be thrown away.
