50 High-security, Low-Profile pin backs (~7mm tall, 10mm dia)  Clasps to keep your pins, medals, insignia, wings, etc., securely attached to your uniform, vest, pin-book, or lanyard.  Works on "all" pins.  Highest quality, jewelry grade.  

Want to try out just a few? -- search for my other listings under ''10 locking pin backs''   

No more lost pins -- the harder you pull the pin, the tighter it grabs.  Don't think they will work as good as the ones with set screws?  Check my feedback ! ! ! 

Easily released from the rear. No tools required like those other "secure backs" and No set-screws to loosen up.   Just push the back on and it's secure.  Squeeze-pull on the little flange on the back to release (if you pushed it on really hard, push on the body while squeezing the flange to release the pressure on the lock.)

Just like a tie-tack back, but no ball on the end -- now it lies flat.     Type used by Disney cast members to secure their service pins on their nametags.
No pin poke-thru.  Ladies love these smooth, low-profile pin clasps (no more irritated skin from poke-through or rough backs.)

Airline Pilots are buying like mad to keep their wings level.  Also good for military uniform items -- no more loose rank, nametags, ribbons, badges, medals, etc.

No bloody fingers from poking through a rubber back.

No torn fingertips from removing cheap metal backs in your pin book.
