A very handy and complete set that lets you do all knds of cake and cupcake decorating, pastry filling, and macaroon making. And since the pastry bags are made of soft, flexible, stain-proof, dishwasher-safe silicone, they'll last basically forever. The set includes two 12" (17.5 ozs.) silicone pastry bags, one 9" (8.98 ozs.) silicone pastry bags, five decorating tips, one filling injector nozzle, a cleaning brush, a pastry bag cap, a pastry bag clip, and a stand to store everything. The cap lets you store filling in a bag; the clip lets you hold the bag firmly while squeezing and seals the large end of the bag to preserve the contents.
