Baby Castella Maker - 45 Holes - Brand New Uses propane gas. The hole size is 4cm x 3cm, about the same size as those generally sold at food stalls. It's Teflon-coated, so I think it's easy to clean. I think it will be a great success at festivals, event stalls, and the like. *Important Notes Regarding Shipping* If you are in a hurry, please consult with us in advance regarding the number of shipping days.
