Missing its original glass lid. Minor scuffing on the base. Potential utensil marks (grey streaks) inside or on the rim which may require specialized cleaning with Barkeepers Friend.
Selling Guide
Where to Sell
eBay (best for reaching collectors), Etsy (best for vintage enthusiasts), or Facebook Marketplace (best for quick local sale without shipping risks).
Selling Tips
Use keywords like 'Vintage,' 'Pyroceram,' and 'Mid-Century Modern.' Mention the model number P-1 1/2-B. If shipping, wrap heavily in bubble wrap as these are heavy and can shatter if dropped. Do not overprice unless the lid is included.
