Guoxin 200 Sets 9MM Spikes and Studs Kit Metal Bullet Cone Spikes Screw Back Leather Crafts Rapid Rivet Screws Punk Studs for Clothing Belts Shoes Bag Accessories (9MM-Spikes)

This is pretty much a "what you see is what you get" kind of product - These arrived exactly as described.The screw backs are a good length and fit into the spikes well, are easy to turn until tight, and seem to stay put well. The spikes are uniformly shaped and the finishes look nice.I will still probably put a little glue on the threads when I use them in a permanent application, but that is not because of a defect in the product.

Nice assortment and consistency of the quality. Granted, I have large hands/fingers but note in the one picture that these are very small. You will want to use a magnetized (Phillips head) screwdriver to grip the mail end of each set. The rest of the pictures give you a sense of how they look, their finish, and the differences across the four types.
