US Divers OEM used HARD DISPLAY ONLY curved mouthpiece

I have a few of these and when they are gone they are gone. I am selling you the original mouthpiece without the cages for a super stupid super low price. Why are they priced SO LOW? These are getting or are already super hard. They are complete and look ok. They are just hard and not suitable for diving. These are good for DISPLAY only. The wagon wheels must be bought separately.
