RUBYCA 25MM 10 Sets Large Metal Big Tree Spikes and Studs Metallic Screw-Back for DIY Leather-Craft Bronze Color

Well-made, good quality control (all are exactly the same size, fit, and finish), screws all go in straight, really pointy, look pretty, and a great price. Also shipped very quickly.The screws are not long so if you want to attach these to anything thicker than stuff you'd normally attach spikes to (like more that 3/16" maybe), you'd have to find a longer screw at the hardware store. But I don't think very many people would ever need to do that. They'll definitely go through a thick piece of leather and any article of shoes or clothing that a teenager might want to attach these too. But do teenagers want spikes of this color? Are they "steam punks"? I will never know because I am old and only had access to chrome spikes and actual punk when I was that age.Update: I wanted to buy longer screws as discussed above, but these use some weird proprietary threading that doesn't match anything at the hardware store. But you probably don't care. Still five stars.

They are steel, they screw in, it's not complicated. Good item.

Amazing gold colour!!

I admit it doesn’t say it comes with tools so that’s on me but even when I figured out how to get them on anyway the screws aren’t long enough to go through a seam in denim so I’m hardly sure how I’m gonna use them

These were super easy to use. I bought two packs but only ended up using one (10 spikes) and every single one worked, no defective ones. I used them on my crocs and they worked perfectly. The screw part is pretty short so I had to really push them through the plastic of the shoe but once the head is screwed on they don’t budge. Oh and theyre too small to sit in the holes of the crocs, you’d have to like superglue them if you want them to stay in the holes. Over all feels sturdy and like a solid metal, doesn’t feel like cheap plastic. I think theyre great for the price!

These were very easy to apply to my vest. I used an awl to make the holes and it was very simple to screw on the spikes. Nice and sturdy. Great bronze finish.

they are what they are advertised as. easy to use. suggest to use locktite or super glue on the screws as they are kinda small, not a deal breaker tho

These are pretty good. I used them to customize some accessories on my Harley and they worked really good. They are not real big, and the threads are fine, but they all went together very nicely. I used blue LocTite to ensure they do not come undone while I am riding, if you put these on clothing or something else that is subject to wear and tear you may want to use some as well. I ended up having to drill a 1/8" hole to mount them although a metric drill size would be a little more exact, but nobody will notice. This came to me direct from China and took about two weeks to be delivered. Not too bad in my opinion coming from half-way around the world. I would recommend this product and the seller.
