From the City of Taguig which is part of the Manilla metropolitan area. The stamps were a 2019 joint issue with Singapore celebrating 50 years of diplomatic relations. On the right is a Common rose butterfly which is the national butterfly of Singapore. And on the left a Luzon lacewing butterfly which is endemic to the Philippines. The stamp values and "Philippines" are printed in red foil. The stamps are much nicer than they appear in this scan.
