Make Your Mornings Happier With Cynthia Magic Coffee Mug

Not a morning person? Well, most of us aren’t so getting up in the morning for us is a constant battle with leaving our comfy bed and having to go to work or school. The only time most of us get some sort of life in us is when we drink that first cup of coffee.So we at Cynthia have decided to tackle that dread of the morning by making your cup of coffee just a little bit more exciting. Here’s how it works--pour your normal cup of Joe like you do every morning--except pour it in our special Changing Magic Coffee Mug!

This is heat activated so it is made specifically to react to you pouring a warm liquid in it. You can pour in coffee, tea or even hot chocolate into the cup in order to activate it. After pouring in the hot liquid the cup begins to change appearance!Slowly it will be an interesting pattern! You can’t help but laugh a little out of amusement for this transformation. We have made your morning happier and brighter in seconds--just like magic!

Heat-activated mugs are not only a great fun start to the day but they are also a great way for you to tell whether or not that cup of coffee you made has been sitting out for too long.Nothing is worse than drinking that cup of coffee you set down and it is ice cold! But with our mugs you can see from the color and face of the mug if it’s too cold to sip on your drink anymore.


1.Don't expose under the sunshine for long time

2.Don't scrape on the printing with sharp tools

3.Wash with hand, not suitable for dishwasher machine.

4.Water temperature should be over 70°C/158¨H,the color changed. Be careful with hot water!

It is a nice gift to your children and your family and friends,they must love it,"Add to Cart"now.
