The Taco Proper is designed to work perfectly with any standard or 'supersize' boxed taco shells. They INDIVIDUALLY support a taco shell so that the shell does not fall apart during filling. Then, they hold each shell upright so you can easily top them off before serving them. And finally- because the patented single taco-snugging design supports each filled taco shell they ACTUALLY PREVENT SHELL BREAKAGE DURING EATING! This is simply something a taco rack of any kind cannot do because a rack is only helpful during preparation and serving. TacoProper Taco Holders remove the limitation of taco racks of any kind. Set includes 12 Pieces.
