Up for sale is an incredibly rare, hard-to-find 3-piece set of vintage Tupperware Ultra 21 ovenware in a beautiful pastel blue. While the vast majority of the Ultra 21 line was manufactured in standard off-white or cream, this set is from a very limited, highly collectible colored production run.
Constructed from Tupperware’s high-performance, hard-engineered polymer, this revolutionary 1980s cookware line is dual-ovenable, meaning it can safely transition from the microwave or freezer straight into a conventional home oven.
What Is Included:
• (1) 1.5-Quart Round Casserole Base (Stamped 1 1/2 QT. - 1.42 LITERS)
• (1) Matching Dual-Purpose Lid / Shallow Baking Dish
• (1) Rectangular Loaf / Cake Pan
Condition:
This rare blue set is in excellent vintage condition. The classic white floral/wheat graphics are crisp, fully intact, and vibrant with no significant scrub wear. The hard plastic interiors and exteriors are clean, showing only light, normal surface scuffs from gentle use over the years. No melts, cracks, or deep utensil gouges. Please review all photos closely to verify the premium cosmetic condition.
Specifications & Care:
• Conventional oven safe up to 425°F (218°C).
• Microwave, freezer, and dishwasher safe.
• Per manufacturer guidelines, always use with a food load (do not preheat empty or use under a broiler).
This is a phenomenal addition for any serious vintage Tupperware collector looking for a piece of kitchen history that rarely hits the market. Items will be wrapped securely and packaged with extra care for safe transit. Please feel free to reach out with any questions before purchasing!
