Hey, thought a few MNers would like this! A mug that keeps your drink hot automatically. Nothing like any rubbish heating plate ones you might have seen before, this has everything built in so that your drink stays at the ideal temperature for longer, perfect if you're sick of coming back to a cold brew!
Glowstone Mug on Kickstarter
It's on Kickstarter, meaning it needs to reach a set number of orders in the next 17 days for it to be made (you don't pay if it doesn't get made). Bit more expensive than a normal mug too, but I think it's worth it if you hate cold tea or coffee!
