Have your old ground glass break on you? Just looking for an upgrade? 
 
This ground glass is hand-ground, made to give you the perfect mix between clarity and brightness. 
 
They are true to size. For example, a 4x5  ground glass will be 4x5 inches, which is acceptable for most cameras. Check your camera to ensure compatibility. If your ground glass must be undersized, select the size of your camera and put your measurements in the box to the right. 
 
Corners are cut at an approximately half-inch radius. If you have one of the few cameras that does not require cut corners, or do not want all four corners cut, please leave a note in the "Square Corners" box to the right. 
 
And of course, while the edges of these ground glass have all been deburred, remember, this is cut glass, so handle with care!
