I put these on my back pack and they broke off within a month. They became bent and scratched up on the 3rd day. If you plan to put them on something still it would look fine, Don't put them on a backpack. t-shirt, or bag.
These pins are poorly made. So far I have had two break and/or fall off of my backpack in the 2-3 weeks that I have had them. I would suggest not putting them on something that moves around a lot.
