Traditionally vegetable tanned intricately folded reindeer leather coin purse from northern Scandinavia. Reminiscent of an iris or countless airlocks in a multitude of cinematic science fiction dramas or space operas. Simply squeeze the sides gently to raise the helical flaps, or else simply invert and shake. The purse does however stay closed when compressed top to bottom which keeps coins inside when kept in a pocket, or the flat compartment of a bag. Measures approximately 7cm in diameter, with a depth in the region of 3cm.
