A vacuum coffee cup is a portable, insulated mug utilizing double-wall stainless steel with a vacuum-sealed, air-free space between the walls to prevent heat transfer. These durable, often rust-resistant cups keep beverages hot or cold for 4–12 hours, featuring leakproof lids, non-slip bases, and convenient one-hand operation for commuting, work, or travel.

• Insulation Technology: Uses double-wall vacuum insulation to maintain temperatures, often keeping drinks hot for 6 hours and cold for up to 12 hours.
• Material: Constructed from high-quality, durable food-grade 304 or 201 stainless steel, which is rustproof, odour-free, and prevents flavour transfer.
• Leakproof Lid: Features a secure, screw-on or flip lid with a silicone sealing ring to prevent spills while on the go.
• Design & Portability: Typically, these cups have a tapered, ergonomic design that fits most car cup holders, often including a non-slip silicone sleeve or handle for a secure grip.
