Kingdom of pentagons: a geometric figure on Belgian stamps

In Belgium, the five-year series "Geometry in nature", which started in June 2018, continues to be published. at that time, a circulation of stamps dedicated to spirals was printed. In 2019, stamps with images of items in the shape of a star were released. Five new products presented this winter demonstrate the diverse beauty of pentagons. Each of them can be used to send letters to European countries.

The stamps depict soap bubbles, the mineral pyrite, and plants. One of the stamps contains images of 15 objects in which you can view pentagons. These are elements of the micro- and macrocosm that are hidden from the eyes and reveal their magnificent diversity only to those who are curious and use modern technologies to study the world. Collectors can purchase a block of five stamps to avoid missing a single instance. Next year, a Supplement will be released with images of round objects, and the series will end in 2022 with stamps dedicated to hexagons.
