Happy Birthday - Heat Revealing Mug
This 10 fl. oz Behind the Lines heat reveal birthday mug is the perfect fun gift to surprise a friend, colleague or family member. Simply add hot water and thanks to a few mischievously vanishing letters, the message on the front makes a funny change!
The message on this cheeky mug changes from
'Happy Birthday. You should go for GOLD. Be a star! Do it all!'
'Happy Birthday You Old B*st*rd'
(only without the censorship!)
The packaging comes with a peelable label, helping you ensure the surprise is kept till the recipient has a well earned birthday tea or coffee!
