Length 17 cm, diameter 2,5 cm. Not a standard optical instrument! The mirrors are positioned along the entire length of the cylinder to give a spectacular view: the image formed by the lenses is multiplied along the entire length of the cylinder, and even a mysterious diffused light comes on as you move it. For a more perfect effect, the mount extends about 5 mm beyond the lens to better capture the light. And the 17 mm wide, silvery metal ring is an aesthetic delight, counteracting the colour refraction caused by the holograms.
