Threaded-Type Snap 15 mm, 10 Sets

Please read the instructions for the threaded-type snap punch carefully before use. Be sure to use a fabric patch to reinforce thin fabrics. A plastic washer, sold separately, can also be used as reinforcement or to adjust thickness. If the material is hard like plastic, a 3‑mm pilot hole may be too small. In that case, please purchase a 4‑mm pilot hole punch, sold separately, for that material. Be extremely careful about your surroundings while working so that children will not be able to accidentally ingest the snaps. After use, keep out of reach of infants and children.
