This is an ultra limited edition offer for right now. We want to launch this material on Kickstarter but need some time to test, develop, prototype and put through the paces before we do. We're going to limit it to 20 rings in total and could be a few months until we're ready to launch so don't hold back.
This can be made in other sizes than listed below. If you don't see your size listed, select the closest size and send us an email after you order. Carbonfi@carbonfi.com
