These seem a little smaller than a zero but I think that is because I’m used to a larger flange to hold the plug in place. I haven’t had much issue with them falling out and none of them have tarnished yet. I can see that the wooden ones might tarnish with age so I would recommend taking them out when showering or swimming. I love the variety in colors and the quality of each set. They’re very unique. I’m very happy with this set.

These plugs are perfect! They aren't too big in flare so they fit beautifully. Most are 2 mm bigger in flare, but these are only 1, making them much more comfortable to put in. They do not fall out of my ears like some ppl have reviewed. I am in love with this purchase. A lot of great quality plugs for an amazing price!!! (My ears are 00g)EDIT: although these plugs are all perfect, I have 1 pair that the stone is chipped /: I am disappointed about this, but other than that, as said before they are perfect.

They are not actually 00 they are smaller and slip out easy so I would go a size up

I love all 18 pieces! They fit great not too heavy I’m a size 9/16 or 14mm. I feel I can change them out easily and they don’t fall out! I will be ordering more very soon.

They all look pretty good except for the opalite but you might want to use the wooden ones for sleeping many of these slip out of your ear quite easy rolling around never had a problem with them falling out while I've been walking running or even taking my headphones off

I'm in love with these plugs. My ears respond best to stone plugs and they definitely are thriving with these. Only thing is, because how smooth the stones are, there's no grip, so often they will slid out of my ears at night and I'll wake up with one or both missing. I've noticed that the wooden plugs have much more grip, but they tend to absorb the natural oils my ears produce, and so I'll only really wear them at night and have no issue.

These were a perfect fit! If your going to gauge yours these were perfect. They don't slip off even while sleeping!
