ThermoFlask Insulated Stainless Steel Coffee Tumbler and Mug Set: Hot for 6 Hours

ThermoFlask Insulated Coffee Tumbler and Mug Set

The ThermoFlask insulated tumbler and mug set is a pair of stainless steel coffee cups for tea and coffee lovers who rarely finish a hot drink before it cools. A 450ml tumbler handles the commute while a 340ml mug stays at home or on the desk. Double-wall vacuum insulation keeps drinks hot for up to 6 hours, so the brew you pour at breakfast still tastes warm well into the morning.

Why This Insulated Tumbler and Mug Set Beats Ordinary Mugs

A standard ceramic mug starts losing heat the moment you pour, and an open top invites splashes every time it is carried across a room. ThermoFlask uses 18/8 food-grade stainless steel with double-wall vacuum insulation to hold warmth in for up to 6 hours. Splash-resistant slider lids close over the opening when you are on the move, and non-slip silicone bases stop the cups skating across a desk or car console. Both pieces are made without BPA and are top-rack dishwasher safe, so they are as easy to live with as they are to drink from.

Small Comforts in Every Cup

• Two Sizes in One Set: a 450ml tumbler for longer journeys and a 340ml mug for home, covering most of the day's hot drinks.
• Up to 6 Hours Hot: sip slowly through meetings or the school run without rushing to finish before your drink goes cold.
• Splash-Resistant Slider Lids: slide closed for carrying and open for sipping, which helps keep coffee off your clothes and car seats.
• Top-Rack Dishwasher Safe: rinse, load and reuse with minimal fuss, keeping a daily coffee routine simple and tidy.

Tumbler and Mug Set Details

For Commuters, Home Workers and Gift Hunters

Take the tumbler in the car for the morning drive and leave the mug on your desk for steady cups of tea through the afternoon. Because the two pieces come as a matching set, it also makes a cosy and practical present for anyone who runs on coffee.

FAQs

Q: Will the lids stop spills if the mug gets knocked?

A: The slider lids are splash resistant, which helps contain coffee when you walk or drive with it, and the non-slip silicone base adds stability on smooth surfaces. They are not described as fully leakproof, so keep them upright in bags.

Q: Can both pieces go in the dishwasher?

A: Yes. The tumbler and the mug are both top-rack dishwasher safe and made without BPA. Placing them on the top rack keeps them away from the hottest spray and helps the silicone bases and lids stay in good condition.

Q: How long will my ThermoFlask set take to arrive?

A: Your order is packed promptly at Kitchen Supplies Zone and sent by quick UK delivery with a dependable courier service, giving a prompt UK arrival so your new tumbler and mug are ready for the next morning brew.
