HongXing 500ml Insulated Steel Mug Foam-Lined Clear Lid | Factory Direct

Most insulated mugs advertise vacuum technology. The 007 Series uses foam — a different thermal strategy for a different use case. A vacuum-insulated mug keeps coffee hot for six hours. A foam-insulated mug keeps coffee hot for the commute, the morning meeting, and the refill — the 60-to-90-minute window that covers most actual daily use — in a lighter body that costs less to manufacture and less to ship, without sacrificing the core benefit of a warm drink in a cold hand.

The 201# stainless steel body has a matte powder-coat finish in four colours: Red for visibility on a cluttered desk, Gray and Black for professional environments, Brown for warm-toned kitchens and home offices. The double-wall construction sandwiches a closed-cell foam insulation layer between the inner and outer steel walls — the foam traps heat without the weight or production cost of a vacuum cavity. The result is a mug that is noticeably lighter than a vacuum tumbler of equal volume and priced at a more accessible retail point.

The transparent PP flip lid snaps down over a full-perimeter silicone seal — tight enough to prevent spills during a desk knock or a one-handed carry, loose enough to flip open with a thumb. The transparent lid serves a practical function beyond aesthetics: the drinker can see the liquid level without opening the lid, avoiding the overfill-and-spill moment that opaque lids create during a top-up.

For wholesale buyers, the foam-insulated mug occupies the mid-tier thermal drinkware position: more insulation than a single-wall cup, lighter and more cost-efficient than a vacuum tumbler. The four-colour matte lineup provides a professional colour range for office supply, corporate gift, and home-kitchen retail channels.
