These are very pretty charms. I'm going to keep one for myself to put on my keychain. I'll put one in a birthday card to one of my cousins, who also is a volunteer sewist like me, and then I'll give the rest to other volunteer sewists, so they can put it on a zipper, or a charm on their key ring.
The sewing machine charms are better than I expected, and a great price. The charms are sturdy and will be the perfect size for zipper pulls. I was afraid they might be flimsy, but they look like they will go through the wash easily. I’m very satisfied with my purchase.
