I bought this and found out that the graphics on the mug are simply liquid adhered decals. These are stickers that are soaked in warm water to bond them to what they are intended to decorate. That's why it cant be washed in a dishwasher. It also means it better not be left to soak in a sink either. Eventually even hand washing it will leave you with a plain blue mug with no graphics, which is pretty near to what I currently have after several months of regular use and absurdly careful hand washing.

I would not recommend this mug(or any other hand wash only mug), as it isn't good for anything more than very infrequent beverage use or keeping pencils in. Your money would be better spent on a mug that uses glazing to affix the decorative designs to it.

The mug is nice but the hot water had no effect on the sketch, ie it did not show any change in the shorelines as a result of warming/cooling

Ok, but do not put in dishwasher

I bought this for my husband and he loved it! He knew not to put it in the dishwasher but accidently/absentmindedly did so last week. Unfortunately several continents are now gone. But hey, it's a cute novelty. In retrospect, not my best purchase. :)

Fun gift

This makes a fun little gift- but it's NOT dishwasher safe. Watch parts of the world disappear with your morning coffee. A little depressing but still a fun party trick...

Nice idea, but it breaks

The mug is nice, and worked as expected. But after some time I have noticed some scratch on the mug. And I stopped using it as I might spill the hot water because the mug breaks or cracks unexpectedly. Having said that, I think that the mug was too expensive. However, maybe I had a bad luck.

I'm on a tight budget right now and this was a perfect slightly humorous gift for Father's Day which spurred lots of conversation.

Just don't put it in the dishwasher; bought this as a gift for my sister and it was accidentally put in the dishwasher by a roommate of hers and some of the land was washed off. Otherwise, awesome mug!

Funny, but poor quality

I bought this a while back, everyone laughed, I thought it was the greatest thing since sliced bread. And then the paint slowly went away. Now I have a blue mug...
