100 Pairs Cone Spikes Screwback Studs, Cone Silver Studs and Spikes Punk, DIY Leather Craft Cool Rivets Punk(7X10mm)

These are exactly what I needed. They are not too sharp, but they are just right. They are easy to install on your projects -- I'm using it for a denim vest. They are a great size and the amount you get per pack is great. Totally worth it!

They're fine, I just wish there was some in here with longer posts. I wanted to use them on my Dr Martens but the posts aren't long enough to get through two layers of leather and still screw in to the spike.

Easy to screw. Lots of variety. Not too sharp where it hurts if you get poked, but they aren't rounded out either. Great quality. Upgraded these $10 heels.

I haven’t used them yet, but plan to make a spike bra

These specific screws are ideal for jewelry and adding a subtle alternative look to your light jackets, hats, etc. The spikes are a small yet narrow shape with a pointed end, making them stand out nicely without being excessively long or heavy. The screws also hug the spikes like a glove once you secure it to your desired fabric. All the materials come in a small plastic container which is ideal for storing; however, there is no sorting between the screws and spikes themselves, which made it difficult to sort through. The screws are also rather short and dull. I had to use a drilling nail to first poke a hole in the desired fabric I was using, and oftentimes found myself having to reposition the screw someplace else due it not being long enough to go through the hemming on my vest. However, once I finished adding the spikes, they add a lovely touch and made for the perfect subtle touch to your alternative apparel. In summary, these are a good product that I did like and the amount offered in a single package is great. My only takeaways are the lack of organization between parts, and the shortened dull screws.
