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.
