This is a stand for inverting and cooling baked chiffon cakes. It accommodates holes in baking pans with diameters from 18mm to 38mm, so please check the size of the hole in your baking pan before purchasing. If you're currently using bottles as a substitute, please give this a try – it provides stability. For those who wish to purchase two, they can be shipped together for 2700 yen. Please comment beforehand, and I will adjust the price.
