BetterJonny 30 Sets Heavy Duty Snap Fasteners, 12.5mm Gunmetal Black Poppers Press Stud Rivet for Leather Craft Sewing Clothing

This is a terrible product. If I could give these snaps a 0 rating, I would. They are very weak and flimsy, and not made for any type of thick material. They also came with NO instructions, so I printed out the ones online from the description, which are TERRIBLE. I have done a lot of riveting before, but never snaps. I ordered the set of 30 but only needed about 10 snaps--I ruined so many (they bent, pieces fell off, etc.) that I barely had enough for my project. I was doing a coat but not a very thick one, although I specifically did a search for heavy duty snaps. After hours of frustration I got them all put on only to discover they don't snap together! Total waste of time, money, energy and now I have a worthless coat.

I am just getting around to using these Heavy Duty Poppers on a knitted cardigan. I loved them when they arrived and promptly put them aside for when I would use them on my next project. I now find that I am missing all the button inserts for the bottom of the snap (female). Cannot possibly use any of these without that piece. I'm hoping the seller will find my comment and make it right.

I purchased the largest(17mm) and they fit nicely on some thicker fabric. The hook and eye failed on some slacks and this replaced it nicely. Even put some on failing velcro boardshorts. Would not recommend for leather

These snaps split with two light taps. The bulbs in the male side have no where else to go, so it splits the metal on the top part. The connections are loose when they do go together. I liked the price, but I'm getting about 1/5 successful attempts and I know how to put snaps together... proceed/buy with caution.

These are heavy duty. I bought them to use on a bib and they were a bit bulky. Well, I figure the babe won’t be able to rip off the bib, which is a good thing.Update 3/8/21: I’ve used these to make capes as well. I’ve bought these twice and the quality of these is still as expected.
