Nice pins but just take note

I am giving these away for free as thank you/promotional items, and I don't know if these pins would be something I would charge someone for as merchandise. Once the protective film is removed, the acrylic does have a nice shine, but the finish on the outer edge is a little bit rough, I wonder if a fine sanding would make a smoother edge. Also one of the metal pins was faulty in its shape so it would not sit flush on the back of the acrylic, and therefore could not stick.
