Source For Canopy Masks

The Eduard masks are a miracle.  I'm never going back.

Scalemates is a good source for aftermarket products.  Type in the kit your a building in their search bar.  Stuff like canopy mask will populate often times with vendors that offer that particular product.  

Eduard make a lot of canopy masks

Take your pick. E-Bay, sprue brother, many on line sites sell them. But there are not masks for every kit out there and not all masks are the same.
