A "4pcs Double Wall Insulated Hot Pots - Silver" set is a collection of four serving casseroles or hot cases primarily designed to keep food warm (or cold) for an extended period.1

Based on common products available, here are the typical features and specifications you can expect:

• Insulation: They use a double-wall construction, often with a layer of insulating material (like PU foam) between the inner and outer shells, to maintain the food's temperature.2

• Material: The interior is almost always made of stainless steel (food-grade) for durability, hygiene, and rust resistance.3 The exterior may also be stainless steel for a completely silver look, or a combination of stainless steel and food-grade plastic.

• Color:Silver, referring to the natural stainless steel finish.4

• Lid: They usually feature a tight-fitting or twist-lock lid to seal in the heat and freshness.5

• Usage: Designed for serving and storing pre-cooked food like rice, curries, stews, rotis/chapatis, or even cold items like salads.6 They are non-cooking vessels.7
