OK, I am not one to badmouth, but this is something that needs to be said. There is an ebay seller with the user ID, (swfladoug), He sells a visor for the Boba/Jango Helmets and claims that it is the best visor around.
I got mine a little slow, but he made up by including some helmet decals. When I went to put it in, I found that it does not sit flush in the helmet and it is not flexible at all. In fact, when I attmepted to put the slightest bit of pressure to get it flush. the thing snapped in two.
This is no good.
ON the other hand, there is another ebay seller that makes a visor that works great. It is a thin plastic mateiral, that is flexible and very easy to work with. This guy's seller ID is ( firstname.lastname@example.org). He is a great guy and goes out of his way to help you out. I hope that this info helps people in the future from making the same mistake that I did.
I lost $20 on a crappy visor and on a Fett Costume that costs a small fortune to make, every dollar counts.
