This is the Claspgarten Barrel Clasp with CZ Diamonds and a screw mechanism. This is what you want for a heavier, multi-strand piece where security is the absolute priority. * The barrel shape gives it a substantial look that works well with larger beads. * The screw mechanism is super secure—it won't pop open by accident. * The CZ diamonds add that little bit of sparkle, making it a detail piece. * Check the product details for exact sizing and strand compatibility.
