These are 3mm round Rasta Design balls. I have several different styles for 16 gauges. When you purchase message me with the barbell type. The ball design is what is pictured. Because some barbell designs take 2 balls instead of one quantity is based off 2 ball designs vs one ball designs.
I have also included the barbell sizes and shapes via a picture so you can see what I have to offer. I know this may seem confusing, but this is as custom as you get. The picture is the color you get then below you will pick a barbell design. Some barbells take 2 balls some take 1. I'm going to make sure that there is enough for the 2 ball designs vs the 1 ball design listed. Feel free to reach out via the contact us page for more help if you have questions.
