I bought this thinking it would be a great decorative pin to hold shawls in place. I loved it so much I bought three! But I was super disappointed when they arrived. They are cute, but super tiny, only about an inch wide. That's my fault for not reading the description more closely, because it does state the size. But I thought that since it was being advertised as a shawl pin it would have a safety pin type backing, that would allow you to work the pin through your knitting to hold a shawl in place. What it actually has, is a single-point butterfly clutch pin, which won't really work. So this is pretty, but useless to me. Definitely not worth the price.
We are sorry you are disappointed with your butterfly pins. We've heard other members have had luck holding shawls in place with this pin and we do have the dimensions listed on the website. We would love to hear feedback on how we could improve the listing to make the dimensions clearer.
