RUBYCA 100 Sets 10MM Silver Color Bullet Cone Spike and Stud Metal Screw Back for DIY Leather-craft

I bought these because I wanted to put spikes in my Crocs but they’re way too small for the holes. These are not the same size as jibbitz. I’ll find another use for them because I do like them

Easy to use and good for keeping people from grabbing my arm/shoulders. Just stick a screw driver to make a hole and then threat it through and tighten and you're good! I wouldn't recommend washing these in the machine as you might lose them, but I secured mine on the screw threads w some super glue and that seemed to work.

I use a ton of these spikes and lately it seems like the threading is bad on at least half of the spikes. On the bad ones, it's either crooked and I'm unable to use it or there's not enough of it and I have to dig for a longer screw in order to use it. A few of the screws themselves don't have threads at all. Just be aware that they might not all work as easily as they should or work at all really. It seems the tree style spikes don't have the threading issues for some reason, it's just been the cone style that I've had these issues with. I will still purchase because even though some are messed up, RUBYCA are still the best one I've used.

The spike studs arrived quickly and in reasonably good condition. Of the 1000 ordered, less than 5 had damaged spikes (holes in the sides or other deformations). I have used roughly 600 of these spikes and approximately 10 have had issues preventing the screw from from connecting with the spike. I am attaching these through 2 pieces of leather with a combined weight of approximately 6-7 oz and it takes a little effort to attach but once the threads engage they appear to be solid. I would not suggest leather much thicker (or I would use a loctite or other thread locking compound to keep them secure). Overall, I expect less than 25 of the 1000 will be unusable. Note, the picture shows a slotted screw head, mine were phillips head screws (which I actually prefer).

Wow...for the price I was very pleased. Although these are a little smaller than what I expected and the screws are kind of short these are extremely well made and work well for thinner leather items and denim. They worked perfect for my project and I had enough to do my purse (front and back). I used a second set in another color for a faux leather jacket! I had absolutely zero problems with the spike fitting into the screw. Looks awesome and I would purchase again!

Received in good order. And is exactly what it says it is. Small screw-backed spikes for costuming. Worked like a charm. The backing isn't super-large in diameter, so you have to be careful not to make *too* large a slit in the material you're pushing the screw part through, or you might also push the entire back piece through too, by accident. Being a newbie with poking holes in fabric, I messed up once or thrice, but got more accurate later on. Thankfully it was on a dark material and the mistakes were minor. I'm sure probably nobody'll notice my errors. Overall, worked exactly as they should, barring user error. ^_^

I have purchased several of these items from this company, it really is a hit or miss proposition as to the quality of what you are going to get, some of them I only lost 1 or 2 due to bad craftsmanship,ie. the screws don't fit either to bad milling or the lacquer used stops the screw from fitting properly, while other items purchased had a FULL 50% loss due to these variables. My advise is IF you buy from this company is to buy a small amount first to see if it is up to you satisfaction, and then buy the full amount of what you need. If I recall this lot was 90% usable, so take what you will from it. Buyer beware here is high.

Probably some of the best I've used. They're a bit sharp, but nothing that would cut. I bought a pack for a mask I was making and they've held up well and haven't come unscrewed. All we're in great condition.They have a little bit of weight to them, but nothing crazy. I'll probably buy more in the future to just keep on hand -- neve know what will pop up that has me needing these with as much crafting I do.Price is also reasonable for the amount and the shipping was very fast.

Having used yet, but nice delivery

Perfect. Exactly as pictured

Excelente calidad, justo lo que necesitaba

Más pequeños de lo que esperaba y las roscas de mala calidad se pasan
