You're kinda right, saffiano leather is a textured leather and could be described as being "kinda hard" LOL. I would not say it is smooth plasticky feel to it but it is NOT soft like lambskin as an example (buttery).
Anyways, ask the seller for close up pics of the logo, press studs (marked with Prada) and the cards. Saff is pretty easy to fake as are these wallets so you need better pics to be sure.
thanks, will do
