RUBYCA 100 Sets 9MM Silver Color Bullet Cone Spike and Stud Metal Screw Back for DIY Leather-Craft

I got these to add to our dog's collar as a deterrent to possible attack by predators which we have in our area. They are easy to install if you have an awl or leather punch type tool. So far once installed they stay on tight.

Had to buy a few other tools to use these. Ended up flying them one instead.

Pretty good quality spikes. I used my swiss army knife to punch a small hole in my jacket then screwed the spike down onto the screw and it worked just fine. Like most others there were a few spikes that were either missing a thread or wouldn’t screw down due to a messed up thread. Other than that, I got a lot of good spikes for my jacket! I would buy them again, but don’t count on getting 100 useable spikes.

I love this product I used on my sneakers

The spikes worked out very well for my punk vest! I’ve never used this kind of stuff before, and I had no trouble figuring out how to put them on. Thank you! Would recommend!

This is for a jacket. Studs color and quality is nice. But the fact that half the product is defective is not nice. Many of the screw threads don't screw all the way leaving a lot of space between screw and fabric or it just gets stuck and won't twist.

Great quality! I'm using these to decorate my face masks. They're a little heavy for one piece of fabric, but I use soft foam pads to reinforce the mask's shape anyway so not an issue. They are super easy to use. I've been using an extra small phillips head screwdriver to tighten the screws. Very happy with these, I would definitely buy again!

This order took ages to arrive. None of the screws matched the threading inside the studs, so I ended up having to hot glue them on instead of attaching them properly. My guess is either poor machining or mismatched order. The only good this is they were cheap(ish).

Not much to say, you get exactly what you pay for!

Queste borchiette sono fatte benissimo, facilissime da montare, necessitano di un giravite a croce ed una pinza. Consigliate per decorare qualunque cosa.

The 100 set came early, exactly as shown and doesn't look cheap. My daughter was impressed with the quality and how it came inside.

Please give an option to order longer screwbacks these ones don't even go through the brim of a hat. Nevermind my leather jacket. These Just barely go through one layer of denim
