Kalemat fake or real?

Hi,

Stupid question: I received a bottle of Kalemat, that was purchased from UAE. The bottle cap makes a strange noise, like something's loose inside it (big) . It doesn't disintegrate. It reminds me of the noise Spraypaint Bottles make, with the mixing ball inside them.

Performance wise: it lasts like 8 hours total, of which 4- 5 are faint.

Is it a fake, or is it expected at this price range? 218 SR for 50ml

Thanks
