This is a great tool to help speed up your cake decorating. It makes a string of pearls/beads that you can quickly apply to your cake. The mold I have is 8mm, but they come in all different sizes to suit your cake.
I bought mine from NY Cake: http://www.nycake.com/siliconebeadmakerroses11cavities-1-1-1-1-1-1-1-1-1-1-1-1.aspx. If you search on their website for ‘silicone bead’, then all the different options come up.
You can also buy them here:
