Really show the people in your life that you didn't just root around the back of a draw for a shitty card for their birthday but went to town and got them a badge.  
A sweary badge. 
In rainbow colours.  
Because nothing says I love you like, sweary rainbows.
Size wise it's 55mm 
what does that mean in real money? It's the size of a Heinz ketchup squeezy lid: not the 'smack the arse out of the bottom bottle', the  squeezy ones.
