I received 4 of these rings. They're great for keeping various Swiss Army knives and multi-tools within easy reach and don't sink to the bottom of my pockets (that space is already filled with keys, a flashlight, or my phone). They're lightweight and very smooth, so they don't seem to ruin your pants that easily. Contrary to some answers and pictures they do NOT come with a split ring (see photo) which is a bit annoying (as not all multi tools have a split ring as well) hence I deducted 1 star from an otherwise excellent product.
