This is a great present for any Dr. Who fan – I bought this for my mum for christmas along with the TARDIS cookie jar. Unfortunately this is mum's second one of these mugs. When the warning says DO NOT LEAVE IN WATER, it means it. Her mug was knocked into the sink and sat there for about 15 minutes, and the picture bubbled and peeled off. Other than that, the picture holds up perfect when washing, so just don't let it soak and you'll enjoy your mug for a long time to come! :)
