Hello F. Kara,
When I recieved mine it was too poorly packed from factory manual papers were out of the folder but there was no mark on the board it self so I kept it, but I did not find any screw well I guess these boxes are shipped all the way from Italy so anything can happen in between if there is no damage to the board I will suggest keep it especially if you are spending shipping money if the shipping is on seller send it back but I am afraid the third one will look same too.
