These are vintage buttons. The approximate size is about 2cm. There is an "IRIS" stamp on the back. As shown in the second image, a few of them have some plating peeling on the back. These were sold at a craft store, but I received them when the store went out of business. Since they would only be part of my collection, I'm listing them for someone who can use them. As they were sold in a craft store, these are not cheap buttons. They are being sold as a set of 45. #VintageButtons #IRIS #Antique #Buttons #Sewing #Handmade
