why dont you just buy the set. you know the yellow castle. it has four visers in it. just buy it
Matt does not have the resources to buy the entire castle. He is a teenager, I think.
Matt, unless you pay for an entire fig which can run upwards of $10 (if you are lucky) I doubt you will find an old visor.
Even though they look cool, the visors are quite unstable, tend to pop off the helmets, and can bend and damage easily.
Look around at yard sales or estate sales. You might get lucky - like my mint condition, including the box, Knight's Procession for $1
