    Simple, leakproof, travel mug

    I’ve been looking for a leakproof mug with a simple top because I always unscrew the lid to drink rather than flip back the sealing clip. This fits the bill perfectly. The lower plastic top has slots to allow a good but not full flow of liquid and the raised lip should reduce the chance of spillage when in a car cup holder with the lid off. Not used it yet but after two hours the contents measured hotter than my previous mug and was still too hot to drink easily. No complaints with the visual
    quality. Blue is slightly turquoise to my eyes but it still looks good.

    I love these mugs. I have had one for a few weeks now and I find it keeps my drink nice and hot, the screw top system works well and it’s easy to drink from and best of all super easy to clean as no hidden parts you can’t reach like most other brand cups. The finish seems hardwearing and doesn’t scratch and it’s the perfect size to carry. I’m so impressed I will be putting an order in for 5 more which I will give as gifts this Christmas. Price point is excellent and well worth buying right now as theirs is an offer on with money off if you buy more than one cup. I recommend to anyone looking. Yum Asia are a great brand, and their products are always impressive.
