The larger 1/2" diamater Poly-Dowel™ is an interior support for use in heavier cakes. For even more support a 1/4" Poly-Dowel™ can be inserted into the center. They cut with scissors so you will not need to saw them and there will be no splinters like with wooden dowels.
These Poly-Dowels™ have been engineered with a US Patent Pending support system for excellent weight support. They are made from Food Grade Plastic so they can be used in your cakes with no worries. Disposable, single use only - for sanitary reasons.
