This is one piece of heat-tempered glass to replace the glass that comes with the 2421 Butterfly oven. All ovens shipped since 12/12/2011 were shipped with this heat-tempered glass. It is stronger than the original glass, plus if it breaks, it shatters into hundreds of small circular pieces to lessen the possibility of injury.
For customers who purchased ovens from St. Paul Mercantile prior to 12/12/2011, this glass is offered as a free upgrade. We simply ask you to pay the shipping cost. Contact us with your name and address and we will verify your purchase date and bill you for the glass.
