Review on 30Pcs EuTengHao 9X5.5Mm Silver Pin Keepers Locking Pin Backs Clasp Lock by Jessie Duhon

The pinbacks do not come assembled, so be prepared to install the screw into each of your backings. That being said, they are also not the most secure backings. I compared them to backings I purchased from Disneyland and these are certainly of lower quality. These pinbacks do not close completely; if you close it (without a pin in it) and hold it up to the light you can still see through it, which is not an issue with my Disney pinbacks. Because of this I usually need to attempting putting a pin in 2-3 times before getting it in the right spot to be secure. Overall a decent price for the quantity and I will be keeping them, but I will not be repurchasing from this brand due to the security and convenience issues.
