Thank you for viewing my many products. The tip of the iron has grooves. At the same time as the iron is applied, the central needle pops out and makes a hole for the stamen, so you can make small flowers quickly without losing their shape. I heard that it is no longer in production, so I hope that those who are looking for it will find it useful. Due to the nature of the product, there is some dirt due to oxidation on the insertion part (check the image), but I think there is no problem with use. I have carefully cleaned it before listing it, but it is a amateur cleaning, so I don't think it's perfect. Please consider purchasing it with the understanding that it is a used item that has been stored for a long time.
