Cheap watchband

Anyone know where I can buy one of those black rubber-like watchbands typically found on Casio watches? I think they call the material "resin."

See the watch repair store in the plaza on Calle Ciruelas near the corner with Benito Juárez. You'll see it. And if they don't have anything you like, there are several more in the same plaza. They have EVERYTHING there!

Found it! Best collection of Casio and other similar watchbands I've seen. Tiny shop crammed with expertise! Reasonable prices and immediate service.
