Review on 100 Pieces of Mini Silver Metal Hoop Eye Pin Screws: Perfect for Arts & Crafts, DIY Jewelry, Charm Bead Projects, and Cork Top Bottles! by Kim Sanchez

Perfect! They are tiny - see photos in other reviews. Just what I needed to make keychains from plastic character minifigures. I've used over half of these and couldn't find any unthreaded screws and had no breakage when inserting into plastic with pliers. I was a bit skeptical after seeing reviews of threading issues (and wondering if the threads alone wouldn't be good enough to "grab" the charms) and screw breakage, but I've encountered neither of these issues. If my project goes well enough, I'll be buying more of these soon.
