20 Lakeland Duo Colour Large Piping Bags 5 "Duo colour icing kit" louise 20 September 2012 Amazing product! I was so pleased to see this product when I wwas browsing on the Lakeland site. I really enjoy baking all types of cakes and often share them around, either to work colleagues or family members. After decorating my cakes with the duo frosting bag which was extremely easy to use and allowed me to create many different 'duo' frosting, I was amazed at the results- they looked just like shop bought cupcakes. I will definitley be buying this product again and so will my colleagues and family. Well worth the price too!
