Mine appear identical to those pictured in the link. They are smaller than some panniers I have seen but work well for groceries on a small shopping trip and are far & away the cheapest I have found. When its raining, I fit a plastic grocery bag over the canvas pannier as the heavy vinyl outer cover doesn't protect from wheel spray.

The largest load (probably the limit for these) I have successfully carried in two panniers was a 1 gallon jug of milk in one & two cantaloupes in the one on the other side along with a pound of hamburger & some other fresh vegetables distributed within both. Two half gallon cartons of milk would have been a better fit. I'll try to add pictures with a tape measure included later today. Don

Here's the pics: they measure 9 1/2 X 9 1/2 X 5 inches. The leather is embossed with a Swiss city name plus the year of mfr. Mine are from late 70s & early 80s.
