The types of quality earring hooks you need to buy for making earrings are:
Butterfly Back
The butterfly back is the hook made straight that passes through the pierced ear hole. This makes the earring stay in place. The backing is put reverse behind the year which is why it is called a butterfly back. The earrings such as studs or other small earrings usually have these earring hooks with them. The hook on these types of earrings make them look normal in size rather than small. I prefer buying them because they are not easy to make. Buying only the butterfly components would be suitable for you.
Magnetic Clasps
Well, these backing are not really like the hooks but they are best for adjusting them at the back of the earrings. People use them as they are the best to use with easy fastening method. They have got a spring mechanism inside them which makes them attach quickly without any hassle. Choose easy to use earring hooks such as magnetic clasps as they gently stick to the ear lobe. Keep them away from children as it can be really dangerous if swallowed.
Fish Hooks
These types of earring hooks are shaped like a fish, thus called fish hooks. These are easily wearable and passed through the pierced ear holes. Usually, the drop earrings have these kinds of hooks attached to them. The simple and easy to use style of the hook makes the user buy earrings with such kinds of hooks attached to them. These hooks can also be manufactured by the users themselves. Other than this, you can even buy them from several online jewelry sites.
Latch Back
The hoop earrings are usually seen with these types of latch backs. The latch backs are the types of earring hooks which have got the closing mechanism working in such a way that when you wear the earring, the backings are closed and opened. They keep the earring secure and in the right place. Being a circled shaped backing, they are just snapped upwards after passing through the ear hole.
Doing jewelry making business, one needs to have the supplies in bulk. Just like that making earrings also requires hooks of different types in bulks. I would say that having wholesale hooks for earrings stay the right choice for making earrings in a large quantity. Choose quality hooks from any online forum that sells.
