This Reliable as a Perfect Wristwatch Heat Changing Coffee Mug will leave any potential coffee or tea drinkers embarrassed as the words on the front of the mug change when hot liquid is added to reveal the phrase "A Perfect Twat", which any potential victims won't see until you point it out to them.

Your boss or that really annoying bloke in accounts may think he is getting a nice ceramic mug, but unbeknownst to him as soon as he sits down for a quick cuppa people will get a completely different impression of him! Great gift idea for the grumpy man you know or as a jokey gift for someone in the office.

Mug dimensions: Width: 10cm; Depth: 8cm; Height: 8.5cm. Holds 10 flu.oz.
