It's about time a travel mug does what it says on the tin! I can make a cuppa in this and it genuinely stays hot for hours and hours. Because I drink a lot of tea (or should I say I make a lot of tea that goes cold and then I have to heat it up or throw it away) I wanted something that would keep y drink hot and where I could pour out little espresso sized cups. Now there's no tea being wasted as you pour what you want and the rest stays hot. Top Tip: If you want to drink it straight from the cup. The drinking spout is a good one, but the drink honestly stays boiling for ages so we end up leaving the lid off for ages to cool it down - but only if you want the drink straight away. Review: Better than big brands - Got this as the only one I could find narrow enough to fit the cup holders in my Vito van. But it's amazing, I've previously had big branded travel cups (chillys and contigo) yet this massively out performs them, keeps drinks properly hot for so much longer, the seal is so much more reliable too, and so much easier to drink from with a wide opening ## Features - Premium Quality, Seiko Manufacturing --- Our flask is made of high-quality stainless steel, rust and wear resistant, durable and unbreakable. Keep the drink odor free and long-term temperature lock. Superior powder coated finish, fashionable and timeless, sweat proof, easy grip - Convenient Drinking --- One click opening, easy to open and clean. Round cup mouth fit the lip shape. Push up to close the lock, and push down to open the lock. Prevent accidental unlocking and pack the flask in the bag without leakage worry - Leakproof --- BPA free screw lid, along with the silicone seal ring avoid water leakage. Rubber bottom helps to prevent the coffee mug from sliding and tipping over. Slim cup body fit in most standard cup holders - Keep Drinks Cold or Hot for Hours --- Double wall, vacuum sealed design, reduce heat conduction, keep drinks cold or hot up to 6-8 hours - Easy to Take Away ---Lightweight, leakproof. Pack your insulated mug in your bag, without any worrying about spillage or leak. Take it anywhere you want go, to office, school, travel, parties, and etc. Enjoy the nice day and nice beverage！ ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09PBNQ79F | | Age Range Description | Adult | | Best Sellers Rank | 12,031 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 73 in Insulated Cups & Mugs | | Brand | YINJAM | | Brand Name | YINJAM | | Capacity | 450 ml | | Colour | Black | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 1,117 Reviews | | Finish Type | Textured | | Included Components | Lid, Mug | | Is the item dishwasher safe? | No | | Is the item microwaveable? | No | | Item Dimensions W x H | 6.5W x 21H centimetres | | Item Shape | Round | | Item Weight | 0.27 Kilograms | | Manufacturer | YINJAM | | Manufacturer Part Number | KITCHEN-363 | | Material | Stainless Steel | | Material Features | Insulated | | Material Type | Stainless Steel | | Number of Items | 1 | | Occasion | Back To School | | Other Special Features of the Product | Durable,Premium,Resistant,Reusable | | Pattern | Solid | | Product Care Instructions | Hand Wash Only | | Product Style | Travel mug | | Recommended Uses For Product | Travel | | Reusability | Reusable | | Size | 450ml | | Special feature | Durable,Premium,Resistant,Reusable | | Specific Uses For Product | Cold Drinks, Hot Drinks | | Style | Travel mug | | Theme | Birthday, Christmas | | UPC | 734172880411 | | Unit Count | 1.0 count | ## Product Details - **Brand:** YINJAM - **Capacity:** 450 Millilitres - **Colour:** Black - **Material:** Stainless Steel - **Special feature:** Durable,Premium,Resistant,Reusable ## Images ![450ML Travel Mug Reusable Coffee Cup Insulated Thermal Mug Stainless Steel Leakproof Flask Tumbler for Hot Cold Drinks (Black) - Image 1](https://m.media-amazon.com/images/I/51OdMvX5hKL.jpg) ## Questions & Answers **Q: Is this dishwasher safe?** A: I’m sorry, i don’t own a dishwasher but it’s that sturdy and withstand most anything!
