These 10-ounce glass custard cups are ideal for making and serving individual baked or frozen desserts like crème caramel or ice cream. The oven-safe glass transfers heat steadily and efficiently, so food cooks evenly in any oven. Pyrex glass will not absorb or leach flavors or odors, and it cleans up easily either by hand or in the dishwasher. Since 1915, Corning Pyrex cookware has been a vital part of every kitchen, and because it is safe in the oven, freezer, and microwave, it is even more versatile today than when it was first introduced. Pyrex bakeware is covered by a 1-year limited warranty.
