This listing is for a 21mm diameter eyepiece graticule for a microscope intended to fit inside a standard diameter 23mm eyepiece.  It's got a central horizontal 0 to 100 scale with gradations.  The scale font is very fine and perfect for a graticule.

This eyepiece graticule will be very well packaged and sent by Royal Mail upon receipt of cleared funds. 

Thanks for looking - please check out my other listings if you get a chance.
