The fake NINA is on the left.
1. The glass of real perfume Nina Ricci has own colour ( perfume Nina has red glass). Fake bottle has white transparent colour, and perfume (!!) has red colour.
2. Each (!!) Nina Ricci's bottle has own number engraved on a bottle's side (small sign, about 4mm.x7mm.), which is absent on fake bottle.
3. The letters on the bottles bottom of fake perfume have bold type and easily can be removed, because they are just painted. The letters on real bottle are elongate and non-bold, impossible to remove, because they are engraved.
