these are the current room keys from the SANDS REGENCY in RENO they are from the 3 towers. Dark blue REGENCY TOWER. Green DYNASTY TOWER. BROWN the EMPRESS TOWER. they were out of the EMPRESS TOWER regular key so if any one has one that says EMPRESS and brown. I would gladly buy or trade for it thanks. OH yes I personnaly got these from the front desk at the SANDS REGENCY so i will vouch for them. this set is duplicate and up for trade or will list on EBAY thanks
