Cello is renowned brand in market and we trust them. Product quality was upto the mark, but product was having few patches of white color, apart of this middle flap is not fitting well, means one side when fit properly then opposite will not, this is because of dimension variation. This thing's need to be checked at manufacturing end during final inspection. Or the product procure by trader was of second quality which have manufacturing defects. Amazon should check with their reseller so that customer receive first quality product as we trust Amazon and not reseller.
