These studs are made from thick metal, therefore, they will not fall off easily... at all.
(broke one of my screw drivers putting the third stud in :( lol)
Even with this being said, please treat your bags with a little care. I have not yet mastered infusing cockroach DNA with these bags, so they will not survive a nuclear bomb. <3
I've also noticed the picture makes the spikes look dome shaped but they're not. They're pointy. Also, keep in mind that because these backpacks are hand studded, they are not all exactly the same, but come extremely close to the one in the picture.
