Review on Secure Your Pins With EuTengHao 30 Piece Gold Locking Pin Backs - 9Mmx5.5Mm Keepers by Craig Kimball

They come in individual packs of about 10, so I was able to easily give some to my friends.They come with an Allen wrench in each bag too. I find they went on and tightened down with no issues at all. I use them to hold military pins on my ballcap, and they work perfectly. No more concerns about cutting my forehead with the clasps most oins come with.My friends used them to hold Disney pins on their lanyards ave didn't lose any on their trip to Disney.Overall, I'm completely happy with this product!
