'I'll be surprised if they don't sell out'
Amanda Melly, assistant manager of the factory shop, said: "I think the mugs are really good fun.
"It's brilliant because it's such a great cause which does good things for the city.
"They really fit in with the rest of our ranges and the discounted price means that they're more accessible for people who can't usually afford Emma Bridgwater."
Rachel West, who works in the decorating studio, said: "It was really exciting to see the Comic Relief aprons on the Great British Bake Off. I love the show so I was really proud to see our products used by celebs. I'll be taking part in fund-raising by doing a bike ride and we're holding a cake sale too."
Irene Amos, who works as a lithographer in the factory, said: "It does make you feel good to work for a company which wants to do something for charity.
"Our mugs are really popular, I'll be surprised if they don't sell out.
"I've even been asked to send one to my sister-in-law who lives in America."
Lorraine Leese, who is also a lithographer, said: "I've worked here for six years so I'm really familiar with all of the mug designs.
"My favourite Comic Relief mug is the one that says 'What do you call a fast cake? A scone'.
"They have Matthew and Emma's humour all over them and it's appropriate because the theme of Comic Relief this year is 'do something funny for money'."
