This is an original design postcard by "Machino Irodori," a specialized creator of animal-themed goods. All sea turtles are endangered species, and the Leatherback sea turtle is considered the most critically endangered. The Leatherback sea turtle, the largest living turtle, has characteristics not found in other sea turtles. Data on these features has been extracted, compiled, and designed in a museum exhibition style. *For each postcard purchased, "Machino Irodori" will donate 50 yen to a sea turtle conservation organization. The current recipient of the donation is NPO Everlasting Nature.
