Hoop diameter is measured in outer diameter.
All hoops come with a snug and flush connection using a poly carb insert and push button for easy coil up.
If you're looking for a little grip, sanding and gaffer grip tape are always free! However, if you're looking for something more grippy, give 3mm clear grip tape a try. This stuff is pure magic and helps the hoop "stick" to your body. (link below)

If you choose the gaffer grip tape option, please send me a message with your preferred color option. If I don't get a message, I will do my best to choose a complementing color :)
*Each and every hoop is carefully handmade with love and full attention to detail!
