I am planning on making a purse in the near future. Of course I didn't know what I'd need to make one. So thankfully I saw these and it reminded me that I'd need something for the straps. I'm new to sewing and purse making at that. So it was an honest mistake. These rings are triangle. I'm used to the D Rings. However, triangles are supposed to be one of the strongest shapes. That's why they use them for bridges to make sure they are quite sturdy. Trying to pry the ring apart was difficult so it can definitely hold some weight if you're using it for a purse or such. It's a strong metal and doesn't just give. It will do for the purse I want to make. And allow me to do 4 other projects. Happy with my purchase.
