Ear weights are similar to earrings, as they hang down from your stretched ears. You can wear them through tunnels in your stretched lobes, or simply through the hole in your ears so that they hang down. Here's a couple examples:

These can be as lightweight, or as heavy as you like. In this case, the above example is very lightweight. Same for the bottom example:

These Triple Moon ear weights start out as a 3D model that I created, then printed, and finally plated in copper. This process allows me to make the weights any weight I choose. So if someone has incredibly sensitive ears, I can keep them very lightweight.

It's also very important to note, that you should never wear ear weights if your ears are healing from a stretch, or are experincing irritation of any kind. Doing so may damage or irritate your lobes even more.
