Majimaya Original Pre-Seasoned Loaf Pan Set of 3 Brand new, unused. ▪️Product Description▪️ Using specialized equipment, we pre-season the pans with the optimal temperature and time, something you can't achieve at home. The process removes machine oil and increases the adhesion between the base material and the plating, making the pans more resistant to rust and longer-lasting. After purchase, you can use them after simply wiping them clean.
