We generally don’t want that there should be puddle of water on base of cups.
But till now we were not able to solve out this problem in any way.
Now, makers of these new mugs — Ikea’s Trofe Mug state that these have been designed in such a way that water can’t store on them.
I don’t myself trust this but nothing bad in trying as they are very economical, mere 50 cents a cup.
