The dual icing bag is a bag with separate icing compartments to make sure icings do not mix. This allows for more freedom when decorating cakes and cupcakes as different colours and flavours can be used to marvel and delight. The bag comes with a split coupler to keep the icings separate and allows icing to remain in its separate compartments. The bag can be used with different nozzles as long as the coupler is used with the set. Decorating cupcakes and cakes has never been easier with this beautiful icing bag set.
