Clover Wonder Pins, 20 pins per package, 1.25 in. long each. Open and close with one hand! Wonder Pins are a revolutionary pin concept leveraging the benefits of both straight pins and safety pins into a single pinning tool. They are strong enough to pierce multiple layers but thin enough to go through fabric without leaving holes. They are so easy to pin through fabric and always easy to see. Insert the point down through fabric layers and push to expose the thin sharp point. Push down on the closure to either lock in place or release for removal.
