Pure titanium is extremely strong and requires multiple forming stages to shape into a finished baking tray. During this process, subtle horizontal forming lines may appear on the surface. These marks are a natural result of titanium craftsmanship (multi-stage stretching process) and are not considered defects.
They do not impact the tray's strength, safety, non-toxic properties (multi-stage stretching process) or baking performance. Each piece has its own unique finish, reflecting the authentic nature of formed titanium.
