Are these good for sensitive ears?

They are made of 316L stainless steel, which many people with metal sensitivity tolerate well. It is not nickel-free certified, so check with your piercer if you react badly to nickel.

What size is the post?

The post is 8mm long and 0.8mm thick, which is 20 gauge. That fits most standard lobe piercings but is too thin for stretched holes.

How do the backs work?

They are screw-on flat backs. You thread the post through the ear and twist the flat disc on; it holds more securely than a butterfly back but takes more turning.

Can I wear them to sleep?

The flat back is designed to lie flush, so many people find them fine for sleeping. The small heart can still catch on pillows, so try one night first.

Are they sold as a pair?

Yes, one pair of heart studs is included.

Are they good for a first piercing change?

The maker suggests them for a first change, and the fine 20 gauge post and flat back suit healing lobes. Wait until your piercer says the piercing is fully healed.
