The stem of the earring is pretty thick. Therefore if you have small ear holes then the product is no good. They got in my first hole only because it has been there the longest and is more stretched out. My second and third holes aren't stretchy and so the earrings stem is too thick. Wouldn't recommend.

Holes are very tiny.  Found it was best to poke a needle through the hole first before trying to stick and earring backing through it. Bent a couple of earring post before I learned that lesson.

The quality of these earrings is good but I cant wear them because the hoop is too thick. Therefore it hurts my earlobes and are very uncomfortable. I have never had a problem with hoops before.

I bought these because I've lost earrings with fishhook wires when they caught on hair/scarf/collar and pulled out without my noticing. These are quite tiny, and the holes for the post or wire are small (I mean smaller than some similar style backs I have that came with earrings when I purchased them)so it took a bit of effort to get them on some of my earrings, depending on the thickness of the wire. The upside of this is that they should really stay in place.
They are snug enough that I think they would hold post earrings in place, too.
There certainly are more than enough to last me a long time.

I got these because I'm sensitive to metals and butterfly back earrings irritate my ears.

These are very nice looking, quality earrings and comfortable* (see below). HOWEVER, the posts are extraordinarily short. I compared them to regular earring posts and these really are much shorter and slightly thicker gauge.

I'm wondering if these are more for cartilage piercing and not lobes? It was not apparently from the description.

The post barely made it through which made "finding" the hole on the other side of my ear extremely difficult.

Once on they looked great, but fit very tightly. I had to take them out a day later due to some soreness, which I'm hoping was from all the noodling around trying to get them in. I will try to wear them again because I do like them, but I'm not sure I'd buy another pair, just because of the post length.

Unless you have very thin or small earlobes, I wouldn't recommend these for lobe piercings.

The picture led me to believe that these would be heavier and thicker than they actually are.  They are really very delicate and feminine.  The twist is barely seen because they are so thin.  If you are looking for a bold earring that makes a "statement"  these are not for you.  If you want a classic hoop that is very pretty this is a good option.  The finish is quite lovely and they come in  very nice gift box.  Although not what I expected I am really quite happy with them!

The earrings are small and the backs have the pointed tip which is great.  The post itself is very thick and both my girls yelled when they put them in their already pierced ears.  The quality seems good, but the huge post is a detriment if your ears are already pierced.

Issue is that one of the two earrings aren't completely set inside the holder, so when I wear it and walk fast enough, I can hear it rattling in my ear. Otherwise, the build quality looks great and the size being 7mm is just big enough without looking like ridiculous or too small to look a little on the feminine side for a guy.

I loved the idea of the earring but it's not very practical as far as wearing it with a cartilage piercing(hoop earring). I have a pretty small-ish ear and I wanted to wear this cool earring like a cuff but the "arms" on the man doesn't fit quite right on the ear. It falls off and I would hate to loose it so I never wear it. Bummer because I really liked the idea.

Unless you like putting in your earrings in from behind the ear, and pushing the post forward, this earring is difficult to put on. Definitely not for an upper ear/cartilage piercing, as shown.

These are cute.. they are alot smaller than this makes them appear. If you have the cartledge on up in your ear pierced...like where the ear cartledge makes its' appearance they would be cute for a teenager with short hair. They are a little small especially for long hair for older women where your ears are normally pierced. Putting your hair up away from your face..these would or will be cute. Whatever your preference.. they are very cute and for us older women... that remains a total "of your own" preference...not for thicker ear lobes just too tiny even for my skinny ear lobes but you know you have it on..thats all that matters.

You don't find too many people wearing earrings like these. I love that about them. They seem to be of good quality. They are a little loose and have to be pushed up frequently. I solved this by adding some tiny earring backs that I had on hand from another set of earrings. The earring backs I added are clear and round and I slide them down the back pin to hold the earring in place. It works perfectly and makes the earrings fit snuggly.

These are actually adorable, seemingly well-made earrings, but they are extremely heavy, and I cannot wear them in my ears. Have you seen the old ladies with droopy earlobes? Earrings like these are surely part of the cause.

I'll be converting one into a necklace, as they're too cute -- and seemingly good quality -- to get rid of/return.

The wire to go in your ear is too thick. I like the earring just can't wear them.

The gauge size for the earrings are a little bit. I'd say they're about a 10, so if you were pierced with a 14 or 12, or you just wear smaller sized earrings, these will stretch your holes out a little. Just remember to clean before and after each use if this happens to you.

I got these specifically for the small ones to wear in my cartilage piercing, even the smallest is a little bigger than what I'd prefer. Also, my piercing goes straight through, so a curved earring is a little uncomfortable.

I saw these and had to have them (purchased the Tibeta Craft Boho Tribal Wooden earrings also) because they were unique a pretty. They're also difficult to get them in your ear. The pic that goes thru the hole isn't small enough to pierce thru my earring hole. Disappointed, they sit in my jewelry box adorning it.
