These buckles are an upgraded version of our buckles foe the Minimalist Gym Rings and the MultiStraps. Based on user feedback we have improved user friendliness and quick-setup further.
Our buckles are made from 100% recycled aluminium. We also do not coat our buckles to prevent unnecessary chemical treatment.
Aluminium naturally creates a protective layer from oxidisation and corrosion will not penetrate the metal, unless its used and kept in a very special, or extreme ambient environment is.
