That looks like a Tappit mold, made by FMM.
You can find tons of cutters and molds, including Tappits at Global Sugar Art.
it is a tappit.. buy them from global sugar art... nicholas does have them in his store at his school.. directions come with it.. also on globalsugarart.. i do believe they have instructions on their site to help you also..hth
Not sure about those specific ones, but Lindy Smith has similar ones as well.
Thanks! I finally found it on Global Sugar Art! Yeah!
