Oh, there is also a lunch box insulation cabinet. Take-away lunch box insulation cabinets are divided into single-door and double-door, with large inner container capacity, which can meet the insulation needs of various foods. The cabinet is forged with national standard 304 stainless steel, and the high-density polyurethane full foam cabinet is efficient in heat preservation. The hot air circulation heating system heats quickly and evenly, which solves the problem that the takeaway lunch box is too large to keep warm. Take-away lunch boxes and insulated cupboards are easy to push and pull.
