Surplus Linen Testers

All these linen testers have longer than normal focal lengths. They will work fine if you are near sighted & take off your glasses or are younger than 18 (your eyes can adjust). Otherwise you will have raise them 5-10mm (1/4") off the table to compensate for the long focal length. The 25mm (1") plastic linen tester also has incorrect ruler markings in addition to a long focal length.
