18 SWG / 16 AWG (1.2mm)
Please note that the rings have been sorted by weight equalling approximately 100 rings per bag.
These rings have been saw cut for cleaner closures and are great for learning as they are inexpensive. Because the metal is bare there can be a grey ‘rub off’, this can be washed off. If you need super shiny rings, then take a look at the silver anodised aluminium.
