Designed for professional bakers and chefs for heavy-duty, extended use, this reusable pastry bag is perfect for imaginative cake decoration, food displays, pastry piping, and myriad other uses. The cotton canvas exterior is easy to grip, so you can pipe with ease, and the smooth polyurethane plastic coated interior is leak-proof and ideal for oily product in addition to regular cake and cupcake frostings. The pastry icing bag will accept small piping tips without a coupler, so you can pipe glaze, icings, and frostings with whatever tips you have available. Or you can trim the bag for use with a coupler (Winco CDTC-2, sold separately), and use larger tips to pipe choux pastry, thick dough, or mashed potatoes. The reusable pastry bag is easy to clean, so it's far more environmentally friendly than disposable bags. Once clean, the 18" white, plastic coated canvas pastry bag has a convenient loop to hang it for storage.
