This is a replica model of the "Roman Dodecahedron," an out-of-place artifact (OOPArt) unearthed from the Roman era. The Roman Dodecahedron is an ancient OOPArt produced in various parts of Europe from the 4th century BC to the 3rd century AD, but its purpose remains unknown. This product is a brass casting of the Roman Dodecahedron created by the Bulgarian artisan K. Romanov. The approximate diameter is about 6cm, and each face of the dodecahedron has holes. Small spheres are also attached to each vertex. It can be displayed as a work of art, but it's also a size that fits perfectly in the palm of your hand, so you can stimulate acupressure points or use it to relieve stiffness in your back and lower back. As it is a handmade craft item, there may be some irregularities in shape and size. Please check the images and thank you for your understanding.
