We have found two more undeclared mail parcels with lithium ion batteries during build up for Aircraft X and also for [another flight]. This is a daily occurrence of finding undeclared dangerous goods in mail. This mail should not be routed to passenger airlines putting passengers and flight at risk for safety. Someone [tried] to mark off the dangerous goods label which is a safety concern as well as trying to make a piece of mail not look to be containing dangerous goods. There [was] no indication that this parcel would be containing lithium batteries.
