YINJAM Travel Mug Reusable Insulated Coffee Cups Vacuum Insulation Flasks Stainless Steel Thermal Tumbler for Hot Cold Drinks (Black, 510ml)

Seals very well, easy to wash, keeps my coffee warm for a few hours, and the lid is easy to open and close while still being secure

يحتفظ بسخونة المشروبات لفترة لابأس بها

Great size, holds 2 standard cups of coffee. Unfortunately a bit chipped off within the first day of using it. However it still seals, the drink hole still gets covered. Keeps the coffee hot for a decent length of time. Only negative is that it obviously isn't that sturdy.

و كبير اوي عالحقيقة أو مكنتش متخيلاه كدا بالحجم دة..تحفة بجد و اللون الاحمر شيك جدا

Don't waste your time like I did, spending days to find the right flask, just go with this one. I'm trying not to be so biased but the other day, I had to pop out very suddenly, forgot that I had a hot chocolate in the flask, was gone around 2 hours, and came back to find the hot chocolate at a nice temp. Other flasks I've tried before would have turned a hot chocolate into just a... chocolate. I love that it's leakproof, or at least it is to my knowledge. I'd never just chuck a flask into a bag anyway but I've thankfully yet to have any leaks. There's a nice silicone ribbed grip around the flask which makes it easy to hold, avoiding any slippage that you can get from metal. The lit screws on tightly and is airtight with the silicone innards, and closes tightly and securely when you're not drinking from it. The form factor is similar to a Costa cup, just with a bit more heft.Waffling over, I think this is a really good flask and with all the cold weather we've been having, this has been a lifesaver for me during long days at Uni as well as trips to work. Whilst I largely use it for hot drinks, which I find only keeps warm for a couple of hours, it does work with cold drinks too and is a good year-round water bottle for whatever you're drinking. I love mine! Highly recommend this product.
