Dental and Close-Inspection Mirror Glass Small 2mm flat round silver mirror glass blanks precision cut in the UK for suitable dental-style mirrors, demonstration tools and close-inspection instruments. Diameters are available in 1mm increments, helping restorers and equipment makers obtain an accurate circular replacement. These are rear-silvered mirror-glass blanks with wet-finished edges. They are not supplied as sterile medical devices and suitability for clinical, safety-critical or regulated use must be independently confirmed before installation. Measure the holder carefully and select the required diameter.
