Well this mug can't help with that and we advice adding ice to achieve this. You will however look Cooler drinking from this Mug! If you still don't think it is cool enough then Make It Yours by drawing something cool on it with the included chalks! Yes you can draw on this mug and even cooler, you can erase it after!
The mug is Yellow on the inside and not fall resistant but in the end it will handle all your beverage needs.
This mug is cool and seems to be great quality!
I use it daily! (Just to look at the beautiful Cooler Master logo!)
I've not tried to wash it in the dishwasher. So for the time being I've only used manual washing on this beauty!
If you like Cooler Master and want an awesome mug, you should buy this one!
