Zpsolution 925 Sterling Silver Magnetic Necklace Clasps and Closures, Magnetic Clasp Converter for Jewelry Making Supplies, Chain Extender Connect...

I have been using these regularly for several weeks now and they are holding up well. I use it to put my ring on my necklace while washing hands or doing tasks that I cant wear my ring for so it stays safe so I open and close the clasp several times a day and there are no signs of it deteriorating or coming loose, and it has not come undone without my taking it apart. It has a very small clasp that can be a bit tricky to attach the first time, but that is true of any clasp. I view this as a good thing because it means it is less likely to come undone accidentally. Overall these are strong, sturdy magnets that work really well and I would recommend this.

These are magnetic necklace clasps that can also be used on bracelets. It can be difficult to put a necklace on yourself, especially when a clasp is very small, or to put a bracelet on yourself with your left hand if you are right-handed. Using these magnetic clasps really help. These clasps are well-made and work perfectly. I took off one star because there are other packs that give you more clasps for the money.

The sterling silver 925 authentication mark is on each clasp therefore I can confirm they are sterling silver. The strength I am going to speak of is the strength of the magnet. I have my own way to test the magnet's strength. I do not know what is really used to test the magnet's power. 1) If it pulls apart really easy: not good 2) Pulling straight out left and right is moderately strong: this is good and is the standard for most magnetic clasps I have seen. 3) The strength of the magnet will not pull straight out but must be pulled apart in a folding motion or like breaking a pencil in half: this is the strongest which I have seen in some magnetic clasps. It prevents the necklace from being pulled off a person's neck from the front. One must still reach in the back to take the magnetic clasps apart by folding it in half. These magnetic clasps are the standard strength. These clasps are also smaller than the standard magnetic clasps which have a longer clasp body, which is good for delicate chains. One would not want to put a standard size magnetic clasps on a delicate chain as it would look over powering and odd. So it is my opinion these are perfect for all delicate and thin chains. I highly recommend these for their quality.

These are a great size for making bracelets. The magnet is a bit weak due to it's smaller size so they likely wouldn't work well for a necklace. I purchased these for my daughter to make bracelets so it will work for my application. At the current price of $18.99 or $4.75 each, they are a little more than I would expect to pay. If they dropped the price a little closer to $15 it would bepre reasonable for such small clasps.

I'm glad I found these! I purchased the set of four sterling silver clasps/closures in gold and silver. The spring ring connectors are small, but not smaller than most necklace closures,,and you only need to put them on once, or not often. The 925-sterling silver stamp is tiny, but I've pictured where it's located on the clasps. The magnets are stronger than I expected. I have worn a chain on the magnet extender and slept with it several nights. The necklace stayed on, and the magnets held firm. I haven't had any problems with the magnets coming out of their settings-they are holding firmly. I appreciate the helpfulness that these extenders offer in that I can just use the magnet closures and don't need to struggle with putting on my necklaces anymore. As of 6/4/2024, ti's set of four sterling closures is about 19 dollars, which I feel is a fair value for sterling silver. *Please view pictures and any video as I consider them part of my full review.
