IMPORTANT NOTE: The tiny metal post on the back side of the design is intended to be that short! The top is not a stand-alone earring, it must be used in conjunction with your Bioplastic or Bioflex backing. A push-fit labret is inserted from the back side of your piercing, and then you push the top into the hollow portion of the backing that is sticking out from the front of your piercing. Do not attempt to insert the top into your piercing first and then push the backing onto it. This is not the correct method to use, and you will most likely ruin your backing doing so.
The beauty of this type of body jewelry is that you can cut your BioPlastic or Bioflex stud down to size if needed, which is something that can't be done with metal. But don't start cutting immediately after you have it out of the package! Instead, try the backing on first (without the top) to gauge how much length needs to be removed if any at all. You may be able to wear it as-is.
Once your backing fits correctly, you're ready to push in the top and wear the earring! Use the thumb on your non-dominant hand to keep the disc of the labret pushed against the skin on the back side of your piercing, and the index finger of that same hand to stabilize everything (it will look like you're pinching your ear). Next, use your dominant hand to line up the tiny metal post on the back side of the design with the hollow part of the labret. Slowly, but steadily, start pushing the top into the backing while making sure you're supporting the labret with your thumb.
Make sure the top is being pushed into the backing straight. If the top is pushed in crookedly, then you will most likely ruin the backing by stretching out the hollow section which will make it too loose to hold the top securely. New to push-fit jewelry?

Place your non-dominant thumb and index finger in the same position that you used for inserting the jewelry to firmly hold the backing against your skin. Now, use the thumb and index finger of your other hand to pull the top out of the backing. If you're finding this difficult, then try giving the top a little twist as you pull it out.
