This Ateco 905 1 5/8" x 4 1/4" concave stainless steel flower nail is ideal for making professional, concave flowers to top cakes, cookies, and other desserts! The long stem provides a secure grip as you rotate the nail between your fingers and pipe a flower onto the top. The indentation in the head allows you to pipe beautiful flowers and designs that curve inward for a realistic appearance. Once the nail head is greased, simply pipe the petals directly into it and then let the flower dry completely. After it has dried, carefully pop the flower off of the nail with the tip of a knife. The nail's stainless steel construction promotes easy cleaning, and is small for compact storage. It's the perfect addition to your cake decorating collection! Bringing you innovation and quality for over 100 years, Ateco, an August Thomsen brand, has been internationally known in the industry for creating baking tools of superior craftsmanship and design. By continually improving on tools, materials, and packaging, Ateco is dedicated to providing professional bakers with the kitchen essentials they need to succeed in an ever-evolving industry!
