These are the same size as the original gold leaf decals used in the Opera windows in the hardtop of the TC by Maserati.   
 
If your opera windows are all foggy and delaminated, use these to restore them back to new!    Very high quality decal.   
 
If this is outside of your budget, we do have a more economical version, but it's not as nice as these.
 
Price is for 1 decal.
