Hypoallergenic and ease of putting together these are great and they come with rubber backings!Me gustan, casi ninguno viene defectuoso, ideales para mis aretesI only use surgical steel on the earrings that I make. So I have bought quite a few for supplies. Never before have I ever had them come in a very nice plastic container, holding not only the earring findings but a small bag containing the little rubber/plastic stoppers for making sure your earrings don’t fall out of your ear. I intend to turn around and buy at least one more set of these findings. Very good quality.I ordered these for some projects that my mom has going on in hopes that she will make me a pair of earrings! She does a lot of sublimation and got some blanks that can be made into earrings. She has jump rings but no earring pieces. I really liked this set because it also comes with the clear rubber stoppers that keep hanging earrings more secure.There supposed to be 240 earrings and 240 backings in this set to make 120 pairs of earrings. Honestly, I am not going to count them to verify it! They were nicely priced and appear to be close!This set comes in a clear plastic container that snaps closed. I really liked that because most of the jewelry making supplies we have did not come in containers and we end up tossing them in random containers that are bit too big and end up taking up too much room. This would be a great container to reuse later. These earrings do not come with jump rings so if you need jump rings you will have to purchase some but they bottom hoop is not secured to the earrings and can be opened to attach something directly to it that does not require a lot of space. The jump ring will make the earrings more flowing though and it may be necessary to use a jump ring to ensure that the earrings are facing forward rather than sideways when on.Plus for these earring wires:1. They are hypoallergenic and after wearing them I am pleased to say they do not cause any of the discomfort and problems I have found with other ear wires.2. Enough ear wires for 120 pairs of earrings at this price is a GREAT bargain.3. They come in an appropriate size container that snaps shut to keep them all together until they are all used.Suggested improvement:1. They come in an open position and are much more comfortable when they are moved into a closed position and they stay in your ear better too. It is easy to squeeze them shut with your fingers.I have made over a dozen pair with this box and it looks like I haven't used any yet. I am making holiday Santa and snowflakes for presents so I have more than one of the same thing and they all work beautifully. I love to find a good value and a product that does what the advertisement says it will do.Great product for a great price. Works as it should.Although quality control is lacking, I can say these are a good price for a product that does what it’s supposed to. Some pieces were incomplete and a couple were rusted though. I just tossed them and moved along. I have VERY sensitive skin and I am extremely particular with my earrings. I make lots of them and sell them, confident in the fact that these are truly hypoallergenic. I can wear them from morning until night with zero issues. Hoping with my next order will be equally as satisfied.I really liked these! I made more than 200 earrings and still had some left over. I haven't tried them so I can't say if they are uncomfortable or not. But some of the hooks were shaped weirdly like they didn't have time to make them look like a hook. Also some of them where missing the pieces on the bottom of the hook. But luckily I didn't really need to use all of them but overall it is a good product and I recommend it. Stay safe!I ordered two of these and I am glad that I did! One box had 244 pieces and the other had 248 pieces. Both had some extra oddly formed ones and ones missing balls and coils. But these were extra beyond the nice pieces, and I can use them as wire for other projects. So more pieces in total than listed and all of the complete ones were nicely formed and all looked the same. The color is good, they are shiny, and they match my jump rings. I also like the little plastic boxes that they come in. They latch securely and don't pop open.These are great quality, however the box was cracked on arrival but nothing was missing, still got over 246+ hooks, a couple was without the coil/bead but it was expected. Happy with my purchase.The hooks are good and strong, not flimsy like most and the backs aren't too big so they don't fall off but they're still easy to handle. Plus a nice little flat storage container for easy access.Bought these for earring making. The packaging was great. I love that they put the backs into a baggie to keep them separate. The perfect stainless steel colour to match my other supplies. Will definitely purchase again.transport très long mais le produit est bien.
