Thank you for viewing. Although the details are unclear, this is a 4x12 monocular for sale. It's stated to be 40-120x when used with a Z50. After researching online, it seems there's a telescope with the model number Z50, and attaching it to the eyepiece can increase the magnification. The items for sale are the monocular itself, a strap, front and rear caps, and a dedicated case. It's almost unused, but it is a used item. Please consider this with your understanding.
