Ateco Wunderbag 18-inch Reusable Pastry Bag

Of the Wunderbag sizes we carry, the 18-inch is the one for everyday cake work. It holds a full batch of buttercream or whipped cream, and the heavy coated cotton gives the control that thinner bags lack when piping borders and shells.

The Wunderbag is cotton felt with a polyurethane interior. The coating makes it leakproof, lets fatty fillings slide out cleanly and makes the bag easier to clean than canvas. The thickness of the felt also insulates your hand when piping warm fillings.

Compared with Other Ateco Bags

The Wunderbag costs more than Ateco’s Flex and polyurethane-coated 18-inch bags, and it is heavier. In return it is firmer in the hand, and it softens with use. For a lighter bag in the same size, choose one of those. The 24-inch Wunderbag is the next size up. Our Pastry Bag Buying Guide explains where coated cotton fits among the materials we carry.
