Have you ever gotten a hot cup of coffee in the morning and then something took your attention so you came back, it was lukewarm, then you have to microwave it and it just doesn't taste the same?
What about at night you want to make a hot cup of tea and then your phone rings right as you're getting comfy?
What about when you're sick, it's pouring down rain outside, your throat hurts, and you just want a hot cup of SOMETHING to soothe?!
NOW THERE'S A COASTER WARMER AND OH MY GOD I'M ABOUT TO GIVE THESE OUT FOR CHRISTMAS TO LITERALLY EVERYONE.
