These 14-karat white gold patented
LuxLock™ spring-ratchet bullet clutches are universal earring backs that work with virtually all*(see exception below) single- or double-groove
earring posts to provide improved security against loss. The
notch on your post locks into the bullet clutch with an audible
"click," letting the customer know the earring is securely in place.
The clutch releases with firm pressure. Used with a notched post, the clutch
will never slide out of position over years of day-to-day wearing; a safety
feature in the clutch, however, releases the post to prevent injury should the
earring be caught in clothing or otherwise forcefully tugged. If you love your earrings . . . LuxLock™.
*99% of All Smooth Earring Posts are the Same as the Post Marked "A" and are Safe to Use w/Luxlock Earring Backs. Please Note: Luxlock Earring Backs are Not Compatible with the Post Marked “B” Below (Known as Guardian Posts). The 90 Degree Angle of the Notches (Grooves) in Post “B” will Lock the Luxlock onto the Post and May Prevent Removal.
Please Note:
Luxlock Earring Backs Can Also Be Used with Smooth Posts that Do Not
Have Any Notches or Grooves. However, if there are No Notches or Grooves for the
Clutch to Lock into,You will Not Get the Added Security that these
Earring Backs were Designed to Give. On Smooth Posts with No Notches or Groves, Luxlock Earring
Backs Will Give You the Same Security as Any Well Fitting Earring Back.
**Additional Note:
These Earring Backs Will NOT Work with Screwback Earring Posts.
