Donut Robot® Plunger, for Ring Donuts with a star pattern around a consistent center hole.
The Star plunger is an alternative to the Plain Plunger for Ring donuts and 'Old Fashioned' donuts.
Should you choose the Star plunger or a Plain plunger? The difference between them is in the center Hole. The Plain plunger is a bit wacky and unpredictable, and makes center holes with random shapes. The Star plunger produces a hole that's generally rounder, with a Star pattern around it.
The choice is yours, you can order either a Plain or Star Plunger when you order your Donut Robot®. Both Plain and Star plungers are available in 2 sizes, 1-9/16 inch and 1-13/16 inch diameter.
