Perfect round balls, matte, smooth, another little work of art. So great on knits, smaller may work on a shirt, jackets, bigger on coats. Earthy mustard is wonderful with navy. 

Vintage policy: all vintage items are sold as is. They are special works of art from a time and place when design and quality were standard. These are from Italy. The quality, the concept, and attention to detail are all superb. There may be handmade finishes. I recommend always testing any washing. Usually cool water hang dry is fine if on a garment. No dryer. No hot sun. Test wash them on the fabric first. Some buttons were made in two pieces and may need some adhesive repair at some point which can be easily glued back. If there is a major issue please feel free to reach out.
